The process of producing fresh concrete
Concrete is an indispensable material in construction works but good concrete products, quality concrete and how are it manufactured? In this article, we will share some information about the standard concrete mixing and production process applied in a small batching and mixing plant system at a construction site.Concrete is a very important and common construction material for construction. Concrete is used to execute items such as beams, construction floors, concrete piles, precast concrete ...
Concrete batching system
The first step in the concrete mixing stage is to prepare all the aggregate components, including the main raw material components: yellow sand, crushed stone, cement and water.
The hand mixing is done according to a certain formula depending on the concrete grade that people mix in the ratio of 1 xi, 3 sand, 6 or 8 gravel….
Cement used to mix manually (hand mix) is PCB 30 cement. When the mixture of materials is gathered in one place, people mix materials .
While mixing materials, it is necessary to prepare tools such as shovels, baskets to measure materials, rakes to rake stones, ...
When mixing materials first we use dry mixing before mixing to ensure the even mixing of materials such as stone, sand and cement evenly.
When you see the aggregate components mix well and then people pour in water again, so the hand mixing is done many times until the concrete volume is enough for the project.
Nowadays, the development of science and technology is such that even a manual mixer also has a concrete mixing tank, the mixing is no longer as hard as it used to be. sand and gravel according to gradation depending on the concrete required ....
So, what is the process of producing fresh concrete at the mixing plant?
The mixing of concrete at the batching system takes place is not much different from the manual concrete mixing.
At the concrete batching, the materials need to meet the cleanness without impurities, the aggregate must clearly state the origin ...
The concrete mixing at the station is that people mix on a larger scale than the manual mixing, the uniformity of the aggregate will be better than the manual mixing and mixing.
The aggregates are concentrated and put into the aggregate containing trough. Before mixing, the aggregate is weighed appropriately to ensure proper gradation for each concrete grade.
For example, concrete grade 200 needs 300 kg of PC 40 cement, 500 kg of yellow sand, 2000 kg of stone for example.
After weighing aggregates, the conveying system automatically puts the aggregate components into the mixing tank, and the water-containing silos, the additive also automatically pumps into the aggregate components and mixes after completing the above steps. lemongrass of fresh concrete on the boxes of trucks carrying fresh concrete and moved to the works as required.
Ready-mixed concrete is constructed according to the method of pouring or pumping needs construction and stationary pumping works.
The production of fresh concrete, self-mixed concrete and manual concrete mixes only differ in volume of mixing faster, more than manual mixing.

How to check the concrete slump
In construction and civil engineering, concrete slump test (or simple slump test) is the work performed at the construction site or in the laboratory that usually determines and measures the hardness, consistency of samples. Concrete before pouring concrete or casting maintenance, research or experiment samples.
Concrete maintenance technique properly
In the process of building a building, there are many things to be concerned about. Building quality is still the top concern of homeowners, in which concrete quality is a key factor for a "healthy" home. Sometimes the quality of materials (cement, sand, gravel, stone) meets the standards, but still does not give the desired quality of concrete. That may be due to improper preparation procedures such as concrete formwork grafting. An equally important cause is not paying enough attention to maintenance.
