Strict implementation of national standards (GB175), the quality indicators are better than national standards. Cement divided by main technical characteristics: (1) fast hard (hydraulic): divided into hard and fast express hard types (2) hydration heat: heat and low heat divided into two categories (3) sulfate resistance: points in the sulfate-resisting corrosion and high resistance to sulfate attack types (4) expansion: expansion and self stress into two categories (5) temperature resistance: Cement temperature resistance to cement grade alumina content . A booming cement building materials is a professional wholesaler, distributor, sells China Resources Cement, has over 20 years of experience in the building materials industry, customers throughout the Pearl River Delta. Product models: PC32.5 Zhaoqing cement composite Portland cement direct, PO42.5, PO42.5R ordinary portland cement, PII52.5R portland cement. Strict implementation of national standards (GB175) cement, the quality indicators are better than national standards. Has its own fleet, cement transport trailer 8, more than 70 tons of bulk cement models 15, another 15 tons to 45 tons models have more than 10 units, you can self-distribution in accordance with customer demand, can effectively on time, according to quality, amount to complete customer demand. Lian boiling cooking method can only detect the damaging effects of free calcium oxide. Because fire burned more slowly than magnesium oxide, calcium oxide hydration rate, and therefore can not be found with a boiling pot Brewing unrest caused by magnesium oxide, only through the autoclave test temperature, high pressure, in order to determine this phenomenon. The unrest caused by sulfur trioxide, only cold bread method, the flooding method to be tested, after the upcoming test cake in water conservation 28d 20 ℃ ± 3 ℃, and check whether there is instability phenomenon. Because when the temperature exceeds 60 ~ 70 ℃, it will not produce the volume expansion of the formation sulphoaluminate. Due to the national standard of magnesium oxide and sulfur trioxide has been limited provisions content, so the two methods and test pressure steam flooding method generally can not do.
