Causes of concrete segregation The reasons for concrete segregation may be improper pouring and vibrating, the maximum particle size of aggregate is too large, the proportion of coarse aggregate is too high, the content of cementitious material and fine aggregate is too low, and the density of coarse aggregate is higher than that of fine aggregate. Or the ready-mixed concrete is too dry or too thi...

Case When a concrete company was supplying the basement of a construction site, due to the unfamiliar business level of the batching plant operator the tester wrote the concrete mixing design and handed it over to the operator for input. He went to the concrete laboratory to play mobile games, and the operator mistakenly input the cement. The fly ash was used as cement. The problem was discovered ...

Sand is an integral part of concrete. It is generally called fine aggregate, which refers to rock particles with a particle size of less than 5mm. It can be generally divided into natural sand and artificial sand. At present, common sands are: (1) Manufactured sand; (2) River sand (generally used for sand designated for key projects, and ordinary concrete is generally not used due to high price an...

Crushed sand (Manufactured sand) contains stone ash which has two effects on the working performance of concrete. On the one hand, the increase of stone ash content will lead to the increase of water demand of concrete because stone ash will adsorb certain water and additives; On the other hand, the manufactured sand with poor grading is easy to cause concrete segregation and bleeding. Appropriate...

The influence of operation on concrete quality is mainly in the measurement and mixing process. During production, pay attention to the measurement error, the adjustment of overshoot and the grasp of residual quantity in the feeding process to ensure that the measurement accuracy meets the requirements. Special attention should be paid to the following aspects: External materials have a great impa...
