concrete admixture

The purpose of concrete adaptation and admixture adaptation is to adjust the state of concrete so that it has good working performance. In short, a good condition of concrete is that it has good fluidity within 1-2 hours, the various raw materials are integrated, and there must be no separation…

Fly ash is fine ash collected from the flue gas after coal combustion and is the main solid waste discharged from coal-fired power plants. To improve the combustion efficiency of coal, thermal power plants will not directly burn whole blocks of coal. First, the coal needs to be ground into…

1. Classification According to the formation method of sand: natural sand, artificial sand, mixed sand. 2. Fineness modulus: According to the fineness modulus, it can be divided into coarse sand (3.1-3.7), medium sand (2.3-3.0), fine sand (1.6-2.2), and extra-fine sand (0.7-1.5). 3. Shaking screen machine: Each layer of the shaking…

The birth of concrete can be traced back to the Pantheon, built by the ancient Romans 2,000 years ago. The Pantheon’s foundation, walls, and dome are all cast in concrete made from volcanic ash. By 1756, British engineer J. Smeaton discovered when studying the properties of particular limes that harden…

The full name of mineral powder among the three primary adhesive materials for concrete is granulated blast furnace slag powder, which is obtained when pig iron is smelted in a blast furnace (steel-making is called steel slag). It is a melt with silicates and aluminosilicates as its main components. It…

In recent years, polycarboxylic acid mother solution synthesis technology has increasingly matured through several iterations. It has evolved from the high-temperature esterification process of pure water to the normal-temperature tap water method. Dramatically lowers the synthesis threshold of polycarboxylic acid admixtures. Most mother solutions on the market have similar properties,…
