The effect of admixtures on concrete

Concrete refers to cement as the main cementing material, mixed with water, sand, gravel, chemical admixtures and mineral admixtures when necessary, in appropriate proportions, and after uniform Artificial stone is made by mixing, compacting and curing hardening. Concrete is widely used in construction projects and is the main raw material for current building construction projects.

At present, concrete has been used in civil engineering and construction projects such as high-rise buildings, long-span bridges, ocean development and nuclear reactors. The workability, strength, deformation, Durability and other properties are important considerations for concrete quality. However, factors such as weather, temperature, and different cementitious materials have an impact on the performance of concrete. The development of new structures and new processes now requires higher performance requirements for concrete. Concrete must not only have properties such as retarded setting, good water retention, high fluidity, early strength, high strength, light weight and high durability. At the same time, it is required to have low preparation energy consumption, low cost, and fast construction.

In view of the common problems such as poor workability and deformation in the current use of traditional concrete and cement mortar, the concrete admixtures researched and produced by Yulong New Materials Co., Ltd. , can solve the problems in the concrete construction process to a certain extent. Concrete admixtures are substances that are added to no more than 5% of cement beams during the mixing process of concrete, which can improve the performance of concrete to a certain extent. Appropriate addition of concrete admixtures during concrete construction can help increase the strength of concrete, improve the workability of concrete mixtures, save cement, and prevent concrete from being damaged by freezing.

Because the weather, temperature, sand quality, etc. are different in each region, the problems encountered during the use of concrete are also different, so we study these problems We have produced admixtures that improve different properties of concrete. The admixtures that can improve the workability of concrete mixtures include water-reducing agents, air-entraining agents, and pumping agents. The admixtures that improve the hardening time and hardening functions include retarders, Early strength agents, quick-setting agents, air-entraining agents, waterproofing agents, rust inhibitors that improve the durability of concrete, and some other functional admixtures, air-entraining agents, expansion agents, antifreeze agents, colorants, waterproofing agents, etc. . </p
