7. What is cement? How many kinds of cement are commonly used?A: where by Portland cement clinker, a reasonable proportion of mixed materials, a moderate amount of gypsum grinding fine made of hydraulic cementitious material called cement. Commonly used cement are: Portland cement, ordinary Portland

1. What is commercial concrete?Answer: According to the requirements of the demander, concrete mix with cement, water, sand, stone, admixture and mineral admixture and other components according to a certain proportion, after metering and mixing in the mixing station, sold and transported to the dem

What important role can concrete admixtures play in engineering? Concrete admixtures can not only meet the production requirements of segments, but also outperform aliphatic water reducing agents in the production process, strength and durability indexes of segments. The popularization and applicati

Polycarboxylic acid superplasticizer is a third generation of high-performance superplasticizer in modern engineering construction, which can improve the quality of construction projects and is a relatively satisfactory building material in engineering construction.It has a high water reduction, can

Aliphatic superplasticizer is a very widely used concrete admixture, which is beneficial to the preparation of high fluidity concrete, self-leveling concrete, self-compacting concrete and clear faced concrete. Presumably we all want to know, aliphatic water reducer is how to prepare, below, Xiaobian

As we all know, polycarboxylic acid water reducing agent is a new type of water reducing agent. It has been applied in practical engineering since the late 1990s. In recent years, it has been used in some large projects, and its excellent performance has been recognized by many people in the industr

Concrete waterproofing agent can significantly improve the impermeability and waterproof function of concrete, and the impermeability grade can reach more than P25. At the same time, it has the effects of slow setting, early strength, water reduction and crack resistance, and can improve the workabi

Concrete water reducing agent is mainly for concrete construction to make some changes, can be polymerization of concrete, is a high degree of polymerization polymer. Today, Xiaobian to say what is the classification of concrete water reducing agent.Discussion on classification of concrete water-red

In the construction engineering industry, there are many kinds of admixtures, but the most widely used is polycarboxylic acid admixtures. Polycarboxylic acid admixtures have strong dispersion effect, which can improve the fluidity of cement mix and the slump of concrete, but also reduce the water co

The adaptability of concrete and cement is related to the quality of concrete, which may affect the normal construction in serious cases. Therefore, in order to avoid this, it is vital to improve the adaptability of concrete admixture and cement, how to improve it? Xiaobian summarizes a few points,
