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 Testing


Concrete Testing Services

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.


  • Compressive Strength of Hydraulic Cement Mortars – ASTM C109/109M / BSEN 445

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


A range of bitumen testing services is available both on-site and in the laboratory at TCR Arabia. Some of the tests TCR routinely conducts are:

Bitumen Testing


Concrete Mix Design

Concrete Mix Design is a method of selecting suitable ingredients for concrete and analyzing 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


TCR Arabia offers a range of concrete mix design testing services that are conducted both in the laboratory as well as on site. Some of the routine tests are:

Abrasion Resistance
Abrasion Value
Accelerated Cube Strength
Air Content & Alkali Content
Bleeding Test
Block Density
Bridge Load Test
Compressive Strength
Core Cutting
Permeability Test
Rapid Chloride Penetration Test (RCPT)


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


To analyze the quality of bricks, TCR Arabia performs several tests, which include:
Apparent Porosity and Density
Cold Crushing Strength 
Permanent Linear Change (PLC) 
Abrasion Resistance
Creep Test 
Refractoriness under load (RUL) 
Modulus of Rapture

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. 



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


TCR tests tiles on many parameters and some of them include:

Mortar Testing


Mortar Testing Services

Mortar is a mixture of lime or cement or a combination of both with water and sand. It is a paste used to bind together building blocks like stones, bricks, etc. It fills the irregular gaps between the blocks and seals them completely. Mortar is also used to add patterns or colors in the masonry walls. Cement mortar is composed of sand and aggregates of water and is used as a building compound. Water is used to hydrate the cement and hold the mixture together. It also finds application in creating smooth surfaces on walls made up of bricks and another masonry.  


Mortar when mixed is a much thicker substance than concrete and this makes it ideal to act as glue for building materials. It hardens into a stone­like mass and distributes the load evenly over the bonding surfaces providing tight joints.


Few of the routine tests conducted at TCR Arabia for mortar testing include:
In­Situ Metallography
 Reduced Wastage
 Accurate Content of Cement
 Consistent Strength and Quality
 Enhanced Health and Safety on Site
 Reduced Mixing and Labour Costs

Cement Testing

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.  


TCR Arabia offers testing services for cement inclusive of:

Chemical Analysis
Compressive Strength
