Concrete Scientific Principles University of Illinois Urbana Champaign

The role of water is important because the water to cement ratio is the most critical factor in the production of perfect concrete Too much water reduces concrete strength while too little will make the concrete unworkable Concrete needs to be workable so that it may be consolidated and shaped into different forms i e walls domes etc

What s The Difference Between Terrazzo and Polished Concrete

The difference between terrazzo and polished concrete is the cement to aggregate ratio That s probably the biggest difference anyway Cementitious terrazzo is minimum 70 percent marble chip material and 30 percent cement matrix with a Portland cement binder This is pretty much the opposite of regular concrete which is around 70 percent
