Study of Waste Plastic Mix Concrete with Plasticizer

The fresh and hardened properties of waste plastic mix concrete have been studied (CUR Report 1991). A number of concrete mixes were prepared in which sand was partially replaced by waste plastic flakes in varying percentages by volume. Waste plastic mix concrete with and without superplasticizer was tested at room temperature. Forty-eight cube samples were moulded for compressive ...

How concrete is made - material, manufacture, making, how ...

The first step in making concrete is to prepare the cement. One type of cement, Pordand cement, is considered superior to natural cement because it is stronger, more durable, and of a more consistent quality. To make it, the raw materials are crushed and ground into a fine powder and mixed together.

Proper Methods for Placing Concrete Good Construction Practice

2 Concrete situations that call for the very rapid development of strength or rigidity. 4. Color pigments in powder or liquid form may be added to the concrete mix to produce colored concrete. These are usually used with white port-land cement to attain their full coloring potential. See PIGMENT (MATERIAL). Reinforcing steels.
