Product Description:
Water mixing into plastic cement paste, cement sand, stone and other materials to hardening in air and in water hardening powder the water rigid gelled material, Portland cement are limestone and clay as raw material, according to certain proportion coordination, composed of Portland cement clinker, 0% ~ 5% limestone or granulated blast furnace slag, a moderate amount of gypsum the water rigid gelled material made of fine grinding, called Portland cement, divides the P. I and the P. I I, namely foreign known as Portland cement. So the color of cement hardening after similar to the island of England Portland place for building stone, was named the Portland cement. It has excellent construction performance, in the landmark in the history of cement

Product Feature:
(1)Standard cement ratio 3: 1, capacity of 3100 kg/m3
(2)The thickness of cement particles moderate degree
(3)Setting time by dedicated detector for setting time,
(4)initial setting time is not earlier than 45 minutes, final set time not later than 6.5 hours
(5)Cement strength should comply with the national standard
(6)Volume stability, cement volume change during the process of hardening uniform
(7)The standard heat of hydration
(8)Consistency standard

Other Information
In the process of construction, the construction and storage of product and environment may influence the performance of the cement
Matters needing attention:
Don't be affected with damp be affected with damp and hard
Avoid exposure to quick-drying
Avoid negative temperature cold
Avoid high temperature heat
Avoid by acid corrosion
Avoid aggregate is not pure
Avoid water ash more thick
