Self Compacting Concrete. Self Compacting concrete is a type of concrete that is more flowable than the normal concrete and compacted by itself. Not like normal concrete, vibration is not required to compact it. It flows through the connection areas with reinforcements. Most of us know what is the self compact concrete means.
How Concrete is Made. In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains strength to form the rock-like mass known as concrete.
Foamed concrete is a highly air entrained sand cement or cement only slurry with greater than 20% air by volume. The air is created by the introduction of a preformed foam manufactured using Propump Engineering's custom foaming agent (Propump 26), encapsulating bubbles of 0.3-1.5mm diameter.

When pumping concrete for conventional buildings, it is required that the ratio of the maximum particle size of the aggregate to the inner diameter of the pipe should not be greater than 1:3. In the concrete construction of super high-rise buildings, the pumping height is high, and the required pumping …
17/12/2020 · Fine aggregates were manufactured sand (prewashing) and desert sand, and the fineness modulus of manufactured sand was 3.0. The macroscopic appearance of all desert sands is shown in Figure 1 . Four desert grains of sand from the Chinese areas of Kubuzi, Maowusu, Tengger, and Ulanbuh were used, with fineness modulus values of 0.27, 0.30, 1.03, and 0.57, respectively.
