Read More2021-9-2 Artificial sand and mixed sand are mainly used in building construction, municipal construction, transportation, and other projects whose concrete strength grade is below C60. When meeting the corresponding technical requirements, they can also be used for concrete projects such as ports and water conservancy.

Read More2019-7-1 the natural sand can be replaced with artificial sand up to a maximum replacement level of 60% in order to produce concrete of satisfactory workability and compressive strength and also with cracks of lesser areas. Key words: Natural sand, artificial sand, compressive strength, crack pattern.
Read MoreOn a comparative level, artificial sand is a very close match to building sand mostly because building sand tends to be more widely used than any of the other types. In terms of how artificial sand is made, generally, it is produced through crushing up basalt rock or granite rock and due to this is normally greyish in colour.

We can use sand to give a grip to our painting or wall art by combining 2 cups of paint with a ¾ cup of sand. People make sandpaper by gluing sand to a paper. While bunging metal, we can mix sand with clay binder for frameworks used in the ...

Read MoreFly ash is a material usually used in the manufacture of concrete. Its greatest use is as an addition to cement, lowering the amount of clinker. Another use is the manufacturing of low-density artificial aggregates, with similar processes to those used to achieve expanded clay, as shown in Fig. 3.23 (Güneyisi et al., 2015).

These functions can be altering the setting or hardening behavior of concrete, produce different architectural effects, enhance workability, impart water retention and plasticity of masonry, resist water penetration in walls or containment vessels, or reduces the []

With about 10 billion tons of concrete produced every year, it is the most consumed substance in the world, second only to water.. It is also the world’s most widely used material for construction – from bridges to large buildings, concrete forms the very foundation of our infrastructure.

It is used widely in foundations, buildings, bridges, roads etc. Steel rods or wire are placed in concrete in form of cage/mesh which acts as skeleton to form reinforced concrete.

Read More2016-6-2 Keywords: manufactured sand, concrete, artificial neural networks. 1. Introduction. In many countries sources of natural sand for use as an aggregate in construction are becoming scarce as sand pits are exhausted and environmental legislation prevents dredging [1,2,3]. This is driving the need to source alternative aggregates, such as those ...

Read MoreThe firmness of artificial sand is slightly worse than that of river sand, and there is no problem in the use of ordinary concrete. But for concrete members, except admixtures, the lime-sand ratio and the content of stone powder should also be controlled. 3.

The most commonly used aggregates—sand, gravel, crushed stone, and air-cooled blast-furnace slag—produce freshly mixed normal-weight concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale, clay, slate, and slag (Fig. 5-3) are used to produce struc-
Read More2021-11-20 Concrete, an artificial stone-like mass, is the composite material that is created by mixing binding material (cement or lime) along with the aggregate (sand, gravel, stone, brick chips, etc.), water, admixtures, etc in specific proportions. The strength and quality are dependent on the mixing proportions.
Read More2021-8-20 Aerated concrete does not contain coarse aggregate, and can be regarded as an aerated mortar. Typically, aerated concrete is made by introducing air or other gas into a cement slurry and fine sand. In commercial practice, the sand is replaced by pulverized-fuel ash or other siliceous material, and lime maybe used instead of cement [2].
