what happens in the process if to much cement is added to water

Cement in the concrete is a binding material.If more water is added,the binding power reduces. It is analogous to gum which is used for pasting paper.in olden days,the govt dept offices usually purchase neem gum in a solid form and it will be powdered and mixed with sufficient water for use.If more water is used,then the gum will loose its quality of pasting the papers together.

Jul 31, 2008· Best Answer:Water addsvolume toconcreteand yes it does weaken it. It also allowsthe concretemix to become more fluid, and when thathappens theaggregate (rock) that is in concrete starts to easily sink lower and lower in the slab or wall. Then the lighter weight sand,cement isat the top.

The cement (and cementitious materials like fly ash) in the concreteneeds water to hydrate and form calcium-silicate-hydrate (C-S-H) which is the crystalline gluethat holds the concrete together. The water is chemically bound (consumed) during the reaction with the cement at approximately 25 pounds of water to every 100 pounds of cement.

Cement and water form a paste that coats each particle of stone and sand—the aggregates. Through a chemical reaction called hydration, the cement paste hardens and gains strength. The quality of the paste determines the character of the concrete.

The hydration reaction transforms the Portland cement into crystals that weave into adjacent crystals and form a dense interlocking lattice. With the right amount of water this reaction makes very strong concrete - too much or too little water will weaken concrete.

Thewatertocementratio largely determines the strength and durability of theconcretewhen it is cured properly. The w/c ratio refers to the ratio of the weights ofwaterandcementused in theconcretemix. A w/c ratio of 0.4 means that for every 100 lbs ofcementused in theconcrete, 40 lbs ofwater is added.

Thewater-cementratio is the weight of the mixingwaterdivided by the weight of thecement. High-qualityconcreteis produced by lowering thewater-cementratio asmuchas possible without sacrificing the workability of freshconcrete, allowing it to be properly placed, consolidated, and cured.

Mixing bags ofconcreteisn’t complicated. You add somewater, stir it up and pour it out.
