67. Can observation of mixing current predict the degree of dryness of concrete mix?A: Predictable. Because the drier the mixture, the greater the stirring current; The thinner the mixture, the smaller the stirring current. The controller must pay attention to observe and record the stirring current

49, How to treat customers?A: First of all, we should treat customers with polite words and deeds, first say hello and then ask questions, the tone is kind and not rude, and the language is civilized and does not panic; Able to do immediately to do, not lazy people do not delay; Reasonable requireme

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

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

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

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,
