The seven performance of cement - the function of CGM high-strength concrete grouting material Yunnan grouting material manufacturers

CGM high-strength grouting CGM high-strength grouting material price CGM high-strength cement grouting material manufacturer generally refers to the performance of cement used in mortar and concrete CGM high-strength grouting material of water requirement, work performance, Liquidity, plasticity, uniformity and stability and its ability to keep) , setting time, strength, volume stability and durability meets the needs of engineering overall performance. 1, the workability of cement and water requirement of cement performance is the basic requirement of as much as possible on the premise of guarantee of workability reduce water demand. Reflects the cement cement standard consistency water reaches a certain liquid water requirement characteristics. 2, early strength and strength growth project hope to use the cement of high early strength and the strength growth rate high, because this is the need of construction efficiency and economic benefit. Higher early strength of cement, the preparation of CGM high-strength concrete grouting materials by the early strength is high, which is beneficial to speed up the turnover of the template and the engineering construction progress, at the same time can reduce the CGM high-strength concrete grouting material early cracking. 3, volume stability, henan CGM high-strength grouting cement mortar which is good and CGM high-strength concrete grouting material in engineering applications, they should be considered the volume stability of this critical issue. Volume shrinkage and cracking of concrete caused by improper construction control CGM high-strength grouting material strength, durability of permeability and resistance will be different degrees of impact. 4, plus the seam an agent compatibility with cement concrete with the beauty and the compatibility of seam an agent including plus seam an agent and cement in the interaction of CGM high-strength grouting cement mortar and concrete material performance, mechanical property, volume stability, etc, the rationality of the change, adaptability and advantages and disadvantages. 5, the hydration heat of mass concrete CGM high-strength grouting material structures, such as dam, the foundation of the bridge pier, large, due to the hydration heat accumulation in the internal not easy divergence, internal temperature can increase 50 ~ 80 ℃, cause and the external temperature, large temperature difference and temperature stress will result in the crack of the hardened CGM high-strength concrete grouting material. 6, the chemical corrosion resistance, low alkali content of cement and durability at present, people have realized the durability of CGM high-strength concrete grouting material is more important than other indicators. The quality of the cement of CGM high-strength concrete grouting material durability has very important influence. 7, the uniformity and stability of the cement cement used in the automatic control for modern construction industry continuous mechanized production line configuration ready-mixed concrete CGM high-strength grouting material. At the same time of mass production, the CGM high-strength concrete grouting material quality requirements are also higher.
