Aggregate. The process of mixing in the aggregate to the cement paste is called “aggregate placement” or sometimes just “placement” depending on context. There are many different types of aggregates, and some could be used for either coarse or fine aggregate. The three main types are: sand; natural aggregates (rock) manmade aggregates ...
Read More2 天前 Concrete mixing is a process of mixing the ingredient of concrete such as cement, sand, aggregate, water, and admixture together to make concrete of suitable grade. To make the different grades of concrete, mixing of concrete materials should be done properly as per the mix design of concrete to achieve the design strength of concrete.

Sand-gravel aggregate is a general term for sand, gravel, stone and other materials in construction projects, which is the main building material of concrete and masonry stone in hydraulic engineering. Aggregate, a type of granular loose material, acts as the skeleton or filling in concrete.
Read More2020-8-13 The reason concrete cannot be made simply by mixing sand with cement is that it is a composite material that needs a coarse aggregate to achieve this strength. In essence, concrete is a mixture of Portland cement, water, sand, and rocks. The cement or paste coats and binds the sand and rocks. Then, a chemical reaction called hydration, which is ...
Read More2016-6-8 Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in the ratio 1:2:4 or the mix contains one part of cement, two parts of fine aggregate and four parts of coarse ...
