Improper use of concrete admixtures affect the quality and cost

At present, the additive storage testing, most of the wet mix concrete batch plant is a solid content, water rates, density, paste and other technical indicators in the 1~2 test, very few concrete mixing stations.

In practice, we found that even though the additive content of solid, water rates, density, paste and other technical specifications to meet the requirements, concrete tests still may not meet the test results, that is, insufficient water for concrete, bad or adaptability.

Due to the low levels of admixture of low price purchase quality, in order to achieve adequate water and effect technical departments tend to increase the amount of additives, resulting in additive consequences of low quality. Instead, quality control and stability, better cost control of mix proportion of automation concrete batch plant using admixtures of better quality and higher prices, due to low quality, additive cost reduction rather than unilaterally.

Some concrete mixing plant limit the amount of additives. In the case of lack of concrete slump, technology sector or to reduce the moisture content of sand, stone, or concrete unilateral water, directly led to the decline of strength of concrete. Quality-conscious technology sector will be indirect or direct unilateral water consumption of concrete at the same time, increased content of cementitious materials (keep the water cement ratio unchanged), leading to concrete costs increase.

Admixture of concrete mixing plant is a lack of quality control and test validation. Quality fluctuation in admixture (down), the technology sector still uses the original mix. To meet the slump of concrete requirements, concrete of actual consumption increases, water cement ratio and concrete strength.
