Soil is formed by the combination of rock, organic matter and pieces of minerals, air, and water. It is considered to be the skin of the earth’s crust. The quality of soil varies depending on its composition, strength, and type. Poor quality of the soil is one of the critical issues faced by builders. Before starting any construction on land, it should be ascertained that the land is suitable for the planned infrastructure and the soil can bear the load of the proposed building, roads, etc. Problems and errors can be greatly avoided by conducting a study on soil and site characteristics.

The quality of the soil is judged by analyzing those properties which limit a planned use. Various soil and site factors need to be determined in order to check the limitations before constructing a building or a structure. Some of these include: Surface texture, Permeability, Water table, Erosion hazard and Depth of soil and bedrock

Concrete is a construction material that is composed of cement (commonly Portland cement) as well as other cementitious materials such as fly ash and slag cement aggregate (generally a coarse aggregate that has gravel, limestone, or granite, plus a fine aggregate such as sand), water, and chemical admixtures.There are various methodologies for concrete testing to ensure that it maintains adequate strength and durability. If major repairs are to be executed in the concrete structure, it is often useful to check the bond strength of the material used in the concrete structure

Mechanical and physical testing is performed on hardened concrete to determine values such as electrical conductance, the compressive strength of a concrete core, cube or cylinder and classify its durability. Mixing design trials are also carried out to ensure the concrete will exhibit values that are within the normal ranges

BITUMEN TESTING SERVICES

Bitumen is a mixture of organic liquids that are highly viscous, black, sticky, entirely soluble in carbon disulfide, and composed primarily of highly condensed polycyclic aromatic hydrocarbons. It is principally obtained as a residual product in petroleum refineries after higher tractions like gas, petrol, kerosene and diesel, etc., are removed generally by distillation from suitable crude oil.

Indian standard institutions define Bitumen as a black or dark brown non­-crystalline soil or viscous material having adhesive properties derived from petroleum crude either by natural or by refinery processes

CONCRETE MIX DESIGN

Concrete Mix Design is a method of selecting suitable ingredients for concrete and analysing their relative quantities for the production of concrete. The produced concrete should be made as economically as possible with minimum properties, significant workability, durability, and strength. An accurate determination of mix proportions by using computer data is usually not possible as the materials used are essentially variable and their properties are not assessable quantitatively.

Concrete Mix is an extremely flexible building material which can be exclusively designed for strength and it may range from M10 to M100. A mix selection needs appropriate knowledge of concrete properties as well as experimental data especially for the person who is conducting the mix design. The objective of preparing a design mix is to achieve good quality concrete in the most economical way. Good quality concrete is dense, homogeneous and imparts better strength and durability

BRICK TESTING SERVICES

Bricks are categorized as the building blocks of any structural building. Thus, the quality of each and every brick needs to be good in order to avoid any serious damage in the building. A brick is a single unit made from Clay bearing soil, lime and sand or it may also be made up of concrete material.

Bricks are named depending upon their composition such as Burnt clay bricks, Concrete bricks, Sand lime bricks, Fly ash clay bricks and Fire clay bricks

TILES TESTING SERVICES

Tiles are manufactured pieces of materials like stone, ceramics, glass or metals and are considered construction materials. Their major application is for usage in floors, roofs, walls, tabletops and other similar objects. Tiles are categorized on the basis of the applied manufacturing process and are classified as per their water absorption level.

NBL Engineering is proficient in evaluating the performance of glass tiles, acid resistant tiles, ceramic tiles, stones, marbles, slates, limestone along with their respective installations. NBL provides testing facilities for all types of tiles as per various National and International Standards

CEMENT TESTING SERVICES

Cement testing is performed to determine if there is alteration/loss of material when in its solid state. Methods of testing include subjecting it to a high temperature to determine loss of material, compressive strength, hand fineness among other factors to ensure that they meet the relevant international standards

CERAMIC TESTING SERVICES

Ceramic materials possess a combination of properties which make them unique and suitable for high-performance applications. Most ceramic materials are metallic oxides like zirconium oxide and aluminium oxide. Metallic carbides are one of the most important classes of ceramics.

NBL Engineering offers a complete range of testing services for all the construction materials including the raw materials and final products as well as quality control services according to the National & International Standards

SALT SPRAY TEST

Salt spray testing is a method of checking the corrosion resistance of coatings and materials used to manufacture products such as fasteners. During salt spray testing, an accelerated corrosive attack is produced in order to better predict how well the coating protects the metal

CHEMICAL ANALYSIS OF FERROUS/NON-FERROUS

Chemical analysis of metals is a crucial process in material science and engineering, providing essential information about the composition, purity, and properties of ferrous and non-ferrous metals. This analysis helps manufacturers, engineers, and quality control professionals ensure that materials meet specific standards and perform as required in various applications

TENSILE TEST AT ROOM TEMPERATURE

The tensile test is a fundamental mechanical test used to evaluate the material properties of a specimen by subjecting it to a uniaxial tensile load. Conducting a tensile test at room temperature allows for the assessment of various mechanical properties, such as yield strength, ultimate tensile strength, elongation, and reduction of area. This information is crucial for understanding how materials will perform under different loading conditions in practical applications

TENSILE TEST AT ROOM TEMPERATURE

The tensile test at elevated temperatures is essential for evaluating the mechanical properties of materials under conditions that simulate real-world applications, such as in aerospace, automotive, and power generation industries. Materials can exhibit different behavior at elevated temperatures, which can significantly affect their strength, ductility, and overall performance

HARDNESS TEST

Hardness testing is a critical process used to determine the resistance of a material to deformation, particularly permanent deformation, scratching, or indentation. It is an essential aspect of material characterization and quality control in various industries, including manufacturing, construction, and metallurgy. Hardness is an important property that correlates with other mechanical properties, such as strength, wear resistance, and ductility

IMPACT TEST

Impact testing is a crucial method used to evaluate the toughness and ductility of materials, particularly metals, under high strain rates. This testing is essential for understanding how materials will behave when subjected to sudden forces or impacts, which can occur in various applications such as construction, automotive, aerospace, and manufacturing

BEND TEST

Bend testing is a mechanical test used to evaluate the ductility, strength, and overall structural integrity of materials, particularly metals. This test involves bending a specimen to assess how it behaves under stress and to determine its ability to withstand deformation without cracking or breaking. Bend tests are commonly used in quality control, material selection, and research and development

REBEND TEST

he rebend test is a specific type of mechanical test used to evaluate the ductility and toughness of materials, particularly metals, after they have undergone an initial bending process. This test is particularly useful for assessing the material's ability to withstand repeated bending or deformation without cracking or breaking, which is critical in applications where materials are subjected to cyclic loading or bending

FLATTENING TEST

The flattening test is a mechanical test used to evaluate the ductility and structural integrity of materials, particularly in the context of welded or rolled metal products. This test involves subjecting a specimen to compressive forces to determine how well it can withstand deformation without cracking or failing. It is commonly used for materials such as steel pipes, tubes, and plates, especially in industries where safety and reliability are critical

FLARING TEST

The flaring test is a mechanical test used primarily to evaluate the ductility and integrity of materials, particularly in the context of pipes and tubes. This test involves expanding the end of a pipe or tube to a specified angle to assess how well the material can withstand deformation without cracking or failing. The flaring test is commonly used in industries such as oil and gas, construction, and manufacturing, where the performance of piping systems is critical
