What is cement concrete
Concrete is an indispensable material for works from: roads, bridges, foundations, buildings or buildings. There are many different types of concrete. In this article SMC concrete we would like to share about what is cement concrete, the pros and cons of cement concrete. What makes this type of concrete a common material in construction works?1. What is cement concrete?
Cement concrete is a mixture of many materials such as cement, sand, stone, gravel in which the cement component is the most important adhesive that makes a solid structure of concrete.
It is because cement concrete is a combination of materials in which cement is the key. The aggregates, cement and water are always in balance with the carefully researched ratios to create the standard concrete required by each work item.
In modern construction, to increase the adhesion, increase the hardness and the amount of concrete, people also use some more construction additives such as waterproofing additives, anti-acid additive additives, slowing down. hydration, ...
2. What are the pros and cons of cement concrete?
Today, many projects are built to serve the socio-economic needs. If you use the same concrete as before, it will cause great loss of quality and money. Therefore, a fresh concrete mixing station (commercial concrete) was born, it has provided a source of high quality concrete for buildings.
In terms of physical strength , concrete has good compressive strength, but not very good tensile strength. Therefore, in constructing works, materials with good tensile strength (for example steel) are arranged to put inside concrete blocks, acting as a load-bearing frame to improve the tensile strength of concrete.
Fresh concrete or commercial concrete plays an important role in all constructions. It helps us with the following benefits: reducing construction area, reducing workload, saving time.
Cement concrete is a very important material widely used in civil construction, industry, irrigation, bridges ... because of the following advantages:
Advantages:
Has high compressive strength varies in wide range from 100, 200 to 900, 1000 daN / Cm2.
Reasonable price
Stable quality and standards: Fresh concrete is ready-mixed and produced at the factory according to strict formulas and procedures, and then transported to the project by the company. Therefore, the quality of concrete is completely guaranteed from the raw materials, the rate of mixing materials ...
Along with that, the concrete samples are also saved for easy analysis, testing and collation. When ordering from the seller of fresh concrete, the recipient easily checks all information on the delivery note, and is accompanied by a product quality certificate (sent after 7 days or 28 days)
Controlling quantity and shortening time: Many industry experts believe that investors should choose fresh concrete instead of ready-mixed concrete to control their budget well, avoiding excess or shortage. Missing materials.
In addition, concreting time and construction level will be significantly reduced (about more than 1 month). The faster the project is completed, the more investors can reduce expenses on warehousing, supervision, management ...
Defect:
The quality of concrete supplied must be measured in standard engineering centers, so the construction contractor needs to find a reputable concrete supplier.
The effects of additives
Improve some properties of concrete mixtures such as:
Increase the fluidity of the mixture
Adjust setting time
Improve their waterproofing properties ..

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.
