Antifreeze and its mechanism: the production of cement products in the winter, due to low temperatures, product strength development was significantly hampered, then the problem is to be solved: the first products to reduce freezing temperatures, so that the products of water after forming in zero degrees Celsius when will not freeze; improve the curing agent in the second reaction rate of the low-temperature conditions Man, cryogenic condensation products promote 迸 sclerosis.
  Coloring agent: Since the end product is sintered cement bricks, clay color close to the original color, to change the color of the article when necessary. By leaving the entire access pigment products bring the desired color, there were still trapped accurate, as it will greatly increase the cost of unburned clay products. After incorporation of grinding slag or ash in the products. Makes products become white or gray, mixed with a small amount of clay products can become red, this is a more practical approach.
