And aggregate adaptability is relatively sensitive to the amount of sand in the mud and rock in the dust content or contain gravel, clay content and even particle size, polycarboxylate liquor production equipment, will significantly affect the mix was state . Practical application shows that: at a fixed additives content, content powder at 1% index slump can only reduce 50 ~ 60mm, sand clay content difference of 2%, in order to achieve the same slump , water consumption increases at least 30kg, and can cause changes in aggregate size of the entire disk concrete segregation, showing its sensitivity. Therefore, the use of poly-carboxylic acid-based additives, should be based on changes in the use of raw materials, adjust production mix proportion. Their water-reducing admixture rate should not be too high, the time not too long slump, polycarboxylate liquor formula, otherwise, would be counterproductive. The concrete proposal in general, the use of low water reduction, mixing ratio design of water less than 165kg, monitor quality admixtures, detection index if there are significant changes, especially when the poor, should be to reduce this material usage in order to ensure the performance of mixing things. Regular sampling of raw materials, the test chamber mix concrete test to detect if there are significant changes in indicators, should be redesigned with the ratio of the production. The second addition of superplasticizer should follow the guidance of experts and by the strict test according to GB50119-2003 "concrete admixture technical specifications", when mixing concrete pumping agent from the ready-mixed concrete plants delivered to the pouring site, may Because of the distance, traffic jams or waiting too long pouring concrete slump loss is too large, so that the construction is not suitable for pumping or pouring, you can use the second method of adding pumping agent, the agent is mixed with a certain amount of pumping quickly into the concrete transport mixer running, to stir, to meet the requirements slump measured after pumping and pouring. In principle, adding superplasticizer concrete, due to unpredictable causes slump loss is too large, the polycarboxylic acid liquor prices to be using the second method of adding water reducer, concrete restoration liquidity, Jingmen City-acid liquor, avoid waste concrete mixture. However, due to the material properties of the concrete mix superplasticizer dosage is quite sensitive, it is easy to create once the excess segregation, bleeding, even stratified, and on the second addition of superplasticizer on concrete performance the impact almost has not carried out research work, so the actual construction on the second addition of superplasticizer or not, the number of secondary added, should follow the expert opinion, and rigorous testing to fully verify its feasibility It can be carried out after sex.
