cement is a national pillar industry, cement production of raw materials and ingredients, there are many, where the concrete is an important one, the following article explain three ways to improve the workability of concrete mix: one, to adjust the number of grout grout gives concrete mixture liquidity. The more concrete mix grout the greater liquidity. But too much grout will lead Mixture cohesiveness and water retention are worse, will produce severe bleeding Gyratory Crusher Prices In South Africa, delamination or Ooze. Therefore, the amount of concrete mix in the grout should be in order to meet the requirements of mobility and strength is appropriate, not excessive. When slump concrete mixture is too small to maintain the same water-cement ratio, due to increase the amount of grout. Second, adjust the consistency grout slurry cohesion determined by the degree of thinning thick grout, grout more dense, less concrete mixture liquidity. In the case of cement consumption remains unchanged, water-cement ratio determines the degree of thinning thick slurry. Water-cement ratio is too large, it will adversely Mixture cohesiveness decreased and water retention, resulting slurry flow, bleeding or segregation. In practical engineering, water-cement ratio is determined based on the strength and durability of concrete required. Then determine the amount of water in accordance with the requirements of liquidity indicators. Under the premise remains the same water-cement ratio, increased water consumption Open Cast Gold Mining Equipment, increased the amount of grout, Mixture of mobility becomes large. Reduce water consumption, the amount of slurry reduced, Mixture of liquidity will be smaller. Third, pay attention to the construction aspects of the impact of the construction of the ambient temperature and humidity changes, the length of time of transport, said feeding equipment, and so will the workability stirring performance equipment and vibration equipment impact. After mixing the concrete mixture, with time and gradually become dry, workability deteriorates. The reason is that part of the water has been with the cement hydration, part of the water is absorbed by the aggregate, part of the water evaporation, condensation, and gradually formed a concrete structure, resulting fluidity concrete mixture. Workability of concrete mix also affected by temperature Gravel Crusher For Sale In Singapore. Because the ambient temperature rises, the water evaporates and the hydration reaction rate, the flow is reduced accordingly. Therefore, in order to ensure a certain construction workability, must pay attention to changes in ambient temperature, take appropriate measures.
