What is Concrete Strength and what are the factors

Excess of water in concrete evaporate leave the voids in the concrete Consequently as the W/C ratio increases the porosity of the cement paste in the concrete also increases As the porosity increases the compressive strength of the concrete decreases This can lead to unnecessary cracking of concrete/surfaces In low grade OPC the

Ready Mix Concrete Ordering Tips vibrating sieve separator

One of the most important factors before ordering ready-mix concrete is knowing the required compressive strength Typically reinforced concrete ranging between 3 500 to 4 000 psi is used on footing and slabs on grade between 3 500 to 5 000 psi on suspended slabs beams and girders and walls and columns normally require between 3 000 to 5 000 psi
