Product models: PC32.5 composite Portland cement, PO42.5, PO42.5R ordinary portland cement, PII52.5R portland cement. Strict implementation of national standards (GB175), 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, in accordance with customer demand and distribution of cement itself Foshan businesses can effectively on time, according to quality, quantity and complete the customer's needs. Cement major technical indicators (a) specific gravity and bulk density: standard cement accounted for 3.1 density usually 3100 kg / cubic meter. (2) fineness: Refers to the thickness of the degree of cement particles. The finer the particles, the faster the curing, the higher the early strength. (3) Setting time: cement mixing with water to condense the time required to start, said the initial setting time. Add water and stir from time to complete the necessary condensation, said final setting time. Portland cement initial setting time not earlier than 45 minutes, final setting time no later than 6.5 hours. In fact, the initial setting time 1 ~ 3h, and the final setting for 4 to 6 hours. Determination of setting time of cement setting time was measured by a special instrument (4) strength: the strength of cement shall conform to national standards. (5) Volume stability: refers to cement volume change during hardening uniform performance. Cement containing impurities, will produce uniform deformation. (6) heat of hydration: the role of cement and water produces an exothermic reaction in the cement hardening process cement plant in Foshan, constant heat released is called the heat of hydration. (7) Standard consistency: refers to the standard cement paste consistency test bar sink when a certain resistance.

Strict implementation of national standards (GB175) Foshan cement distribution, 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.
