Types of Concrete Mix for Any Project
Now that you understand the difference between concrete and cement, as well as the popular mix options available, you can try your hand at mixing your own concrete. The most common of all cement types used in concrete is Portland cement. Concrete Mix Recipe: 1 Part Portland Cement. 1 1/2 Part Gravel.
What Is Fresh Concrete | 8 Properties of Fresh Concrete
Concrete is not recommended to be placed at a temperature above 40°C without proper precautions, as laid down in IS:7861(part 1).. Special problems are encountered in the preparation, placement, and curing of concrete in hot weather. The First 24 to 72 hours after placing fresh concrete are .
Brief Introduction of Cement Production Line
Cement production line is mainly composed of crushing and prehomogenization, homogenization of raw materials preparation, preheating decomposition, firing of cement clinker, cement grinding and packaging process. 1. Crushing. Most of raw materials need be crushed in the cement production process, such as limestone, clay, iron ore and coal.
Transportation of Cement
Cargo residues such as sugar and fertilizers may result in the contamination of cement cargoes. Raw sugar reacts with cement and even small amounts seriously affect the setting and hardening performance of cement. As little as % of sugar, if mixed with cement, renders it worthless. Some cement companies do not allow cement to be carried on ...
Concrete: Manufacturing Process
The concrete is taken through the water in water tight bucket. On reaching the place of deposition the bottom of the bucket is made to open and the concrete is dumped. In this process certain amount of cement is washed away causing a reduction in strength of concrete.
