The total chloride content of aggregate is usually measured to assess whether the aggregate^^s contribution to the total chloride content of a concrete mix will be low enough to prevent the early onset of corrosion of any embedded steel reinforcement.

This test helps in determining the percentage of clay lumps and friable particles in aggregate. Clay lumps in aggregate shall be defined as any particles or aggregation of particles which when thoroughly wet can be distorted when squeezed between the thumb and forefinger, or will disintegrate into individual grain sizes when immersed for a short period in water. Friable particles are defined as particles which vary from the basic aggregate particles in that they may either readily disintegrate under normal handling and mixing pressures imposed upon them by construction procedures, or break down after being incorporated into the work.

This test helps in determining the of a granular material. The size distribution is often of critical importance to the way the material performs in use. A sieve analysis can be performed on any type of non-organic or organic granular materials including sands, crushed rock, clays, granite, feldspars, coal and soil, a wide range of manufactured powders, grain and seeds, down to a minimum size depending on the exact method. Being such a simple technique of particle sizing, it is probably the most common.

This test helps in determining the compaction percentage of an aggregate when loose compared to the same aggregate compacted in a standard manner. It is useful in assessing an aggregate^^s when placed loosely, for example, as a pipe surround material. Aggregate suitable for use as pipe bedding would display a low compaction fraction, indicating it reaches a state of near full compaction under loose placement.

The Aggregate Crushing Value offers a related measure of the resistance of an average to crushing under a compressive load that is gradually applied.

Drying shrinkage is defined as the contracting of a hardened concrete mixture due to the loss of capillary water. This shrinkage causes an increase in tensile stress, which may lead to cracking, internal warping, and external deflection, before the concrete is subjected to any kind of loading.

Flakey is the term applied to aggregate or chippings that are flat and thin with respect to their length or width, Aggregate particles are said to be flakey when their thickness is less than 0.6 of their mean size. The flakiness index is found by expressing the weight of the flakey aggregate as a percentage of the aggregate tested.

• Water absorption
• The amount of water that a refractory can absorb is measured by the water absorption test. The results of water absorption tests are used for quality assurance.
• Test Method IS 1124-1974, IS 13030-1991, ASTM C 97-2009
• Mohs Hardness
• This test helps in determining the hardness of rock. Because granite is a??rock??composed of multiple minerals, only crystals of specific minerals within the granite would be tested for hardness.
• Test Method IS 13630 (P-13) 2006
• Modulus Rapture
• The modulus of rupture (MOR) is the maximum surface stress in a bent beam at the instant of failure. One might expect this to be exactly the same as the strength measured in tension, but it is always larger because the volume subjected to this maximum stress is small, and the probability of a large flaw lying in the highly stressed region is also small.
• Test Method IS ASTM C 99-2009, IS 1578 (P-5)1993
• Dimension Testing
• This test is done to check the dimensional stability of the rock.
• Test Method IS 1130-1969, IS 3316-1974, IS 14223 (P-1) 1995, IS 3622-1977, ASTM C 625, 616, 629, 503
• Thermal shock test
• Thermal shock is the name given to cracking as a result of rapid temperature change. Glass and ceramic objects are particularly vulnerable to this form of failure, due to their low toughness, low thermal conductivity, and high thermal expansion coefficients. However, they are used in many high temperature applications due to their high melting point.

• PVC Flooring tile
• PVC Flooring provides dust-free, noise absorbing, resilient, non-porous, decorative surface. It shall consist of a thoroughly blended composition of thermoplastic binder, filler and pigments.
• Test Method IS 3461
• Frost Resistance
• Ceramic tile frost resistance is defined as the ability of ceramic tile to withstand freeze/thaw conditions with minimal effect. The frost resistance of ceramic tile is dependent on the tile''''''''s porosity and water absorption levels. Frost damage can occur when the variety of ceramic tile absorbs moisture through its pores, causing the water to freeze internally when temperatures drop. Since water expands when it freezes, tension is then exerted inside the body of the ceramic tile. This internal pressure may become high enough to cause cracks in the ceramic tile.??

• Chemical Resistance test
• This test is done to determine the ability of the grade of granite used by a1-safetech to resist chemical attack.
• Test Method
• Breaking Strength
• Rocks are considerably weaker in tension than in compression. Characterizing tensile strength of rocks thus is of great importance in many engineering and geophysical applications. Tensile strength is defined as the failure of stress.
