Grouting material price - Henan grouting material which is strong

grouting material prices grouting materials and grouting material price determining factor now on the market sales of grouting material, brand heavy and complicated, have different price, the quality is good and bad are intermingled. Customers in the purchase of grouting material, be sure to polish eyes, choose the price is reasonable, big brand, big factory produce high-quality grouting material. Don't believe in small workshops of false advertising, grouting material is a kind of high-tech building materials, only the state of state-owned enterprises big factory produce high-strength non-shrink grout material is good quality. Defective grouting material products, the grouting material casting dense with c60 swell after grouting material price, water film around the inside of the aggregate composition, especially a lot of grouting material products, appear a lot of bleeding phenomenon, in aggregate form below water sac. Subsequently, cement hydration ettringite is generated and the calcium hydroxide crystal, because aggregate appearance water-binder ratio is large, so close to the crystallization of the aggregate of these products is relatively bulky crystal, constitute more than the cement paste or mortar pore structure. Quality did not ensure that the grouting material products, in the early, especially in many inner secrete zhengzhou water grouting material manufacturer, interfacial transition zone in the pore size and scale is bigger than the cement paste or mortar ontology. Crystalline compounds such as calcium hydroxide and ettringite, its scale and quantity in the interface transition zone is bigger, also lead to guess transition zone is lower than cement grouting ontology, the conventionality grouting material price is lower. Big factory produce high-strength non-shrink grout material products, cement and aggregate interface transition zone has been greatly improved. 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 , which was dominated by low water/cement ratio, mixed with plus the seam an agent and mineral admixture. Because of low water-binder ratio to improve the strength and elastic modulus of cement stone, cement and aggregate the gap between the elastic modulus is reduced, making the interface water film thickness decreases, and crystal growth of free space. With the activity of mineral fine admixture, after reaction with calcium hydroxide added C - S - H gel, cut the calcium hydroxide crystal content, interface to layer porosity decreased after hardening. Porosity is very low, and basically there is no more than 10 nm macroporous, natural gas hydrates in the calcium hydroxide cuts, so the grouting material price is higher.
