The concrete mix made using granite powder (GP) and iron powder (IP) as partial replacement of sand showed good workability and fluidity similar to normal concrete mixes. 2. The compressive strength of concrete increased with the addition of granite powder (GP) as partial replacement of sand.
Standard Test Method for Compressive Strength of Dimension Stone, and ASTM C880, Standard Test Method for Flexural Strength of Dimension Stone test results are not suitable to use for horizontal (floor) applications where the thickness of the stone tile being used is less than 1¼". Limitations of Thin Stone .

Quality of concrete can be primarily judged by its compressive strength. Numerous methods of NDT are developed to approximate the compressive strength of in situ concrete.
Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0). Lithology is commonly derived during log analysis, so m may be estimated (Table 1). What is needed still is an initial measure of rock strength provided by C 0.
Concrete. Concrete is a construction material that is expertly composed of the correct ratio of additives (natural or rubble granulates – depending on whether rich or lean mixed concrete is being made – and sand) and cement, which has as characteristic feature that it hardens when adding water, thus matching the hardness of natural stone.
Jul 03, 2015· In this study, properties of hardened concrete produced waste marble powder used admixture or fine/coarse aggregate in the concrete were examined in detailed manner. Additionally, it was determined that possibility of usage of these waste in the concrete as admixture material or aggregate affected positively on the hardened properties of concrete.

Nov 20, 2015· Properties of Marble Marble is a highly durable stone and is used for countertops, flooring, stairs. Scientists have tested and documented the full range of granite and all its capabilities. Below is the property range of values for granite. These values determines it''s strength which measures its ability to resist stresses. Marble Property Range [.]

Compressive Strength. Compressive Strength is the stress, in pounds per square inch (psi) that will rupture a stone sample. Very rarely is the compressive strength of a stone much of a factor in stone selection. A column of stone with a density of 160 lbs/cf that is 100 feet tall exerts a compressive stress of only 110 pounds per square inch.
The more compact grained and heavier a stone the harder it is. Due to alternate wetting and drying the resulting crushing strength can be reduced even up to 3040%. Being dry stones allow more crushing strength than when wet. It is the ability of a stone to endure and maintain its essential and distinctive characteristics resistance to decay, strength and
The specification for the floor of a maintenance building called for a 6inch slab thickness and concrete with a design compressive strength of 3000 psi. The actual average cylinder strength for the floor concrete was 3630 psi. Four months after the floor was placed, 10 cores were drilled, measured, and tested in compression.
of concrete samples. The maximum ordinate of the curve (Point C) that marks the transition between strain hardening and softening is called the unconfined compressive strength of the rock and is denoted as Co or qu. Failure takes place continuously from C to D during which
In this project our main objective is to study the influence of partial replacement of cement with marble powder, and to compare it with the compressive and tensile strength of ordinary M20 concrete. We are also trying to find the percentage of marble powder replaced in concrete that makes the strength of the concrete maximum.
