Although the terms cement and concrete often are used interchangeably, cement is actually an ingredient of concrete. Concrete is a mixture of aggregates and paste. the aggregates are sand and gravel or crushed stone; the paste is water and Portland cement.

Concrete is a heterogeneous system of solid, discrete, gradient sized, inorganic mineral aggregates, usually plutonic or sedimentary-calcareous in origin, embedded in a matrix compounded of synthesized polybasic alkaline and alkaloidal silicates held in aqueous solution and com-precipitate dispersion with other amphoteric oxides, this matrix being originally capable of progressive dissolution, hydration, re-precipitation, gelation and solidification through a continuous and co-existent series of crystalline, amorphous, colloidal and cryptocrystalline states and ultimately subject to thermo-allotriomorphic alteration, the system when first conjoined being plastic during which stage it is impressed to a predetermined from into which it finally consolidates, thus providing a structure relatively impermeable and with useful capacity to transmit tensile, compressive , and shear stress.

Concrete Slump

Slump is the measure of concrete consistency and fluidity. is shoes the flow and overall workability of gressly mixed concrete. Simpy put, the higher the slump, the wetter the mix. Four-inch (4") slump is very common with normal weight concrete and is a good for pumping. Slumps that are above average will cause reduced strength, durability, and permeability of the concrete. Admixtures should be used instead of water to achieve higher slumps so that you can maintain the quality of your concrete.
