Functions of Chemical Compounds Present in Cement. Calcium Oxide CaO. It controls the strength gain of cement. It controls the soundness of cement. Deficiency of CaO in cement reduces strength as well as the setting time of cement. Silica SiO 2. It provides strength to cement. Excess of silica reduces the setting of cement. Aluminium Oxide Al 2 O 3
Silica is normally supplied in 2 forms: Dry Powder or Premixed Slurry For Dry Powder: We offer a weighing hopper (cement-like). Since micro silica is 100 times thinner than cement it can not be transferred as cement. The silica screw conveyor has to be used with much lesser angle to provide the adequate material flow.

Activities impacting these materials also vary, including
What is Alkali-silica reactivity? Alkali-silica reactivity (ASR) remains a major durability issue affecting concrete structures, including heavy civil infrastructure, such as dams, bridges, pavements, and nuclear power plants — despite over 70 years of investigations. (See references [1]–[4] below.) How does ASR impact concrete?
Silica. Silica is one of the most common hazards on a worksite, particularly in the construction, oil and gas, manufacturing, and agriculture industries. Silica dust can cause silicosis, a serious and irreversible lung disease. It can also cause lung cancer. Cutting, breaking, crushing, drilling, grinding, or blasting concrete or stone releases.
has been developing its own Software Department since more than 15 years. More than 1500 concrete batching plants operating worldwide provide an enormous feedback for the improvement. Recently this large experience has been transformed into a simple, comprehensive and extremely sensitive electromechanical structure - a MECAS Automation System.
Since concrete contains quartz, these tools throw silica dust into the air. Hazardous activities include: Cutting bricks, concrete blocks, and similar materials with a stationary masonry saw. Cutting masonry, block, tile, or rock with a handheld masonry saw. Grinding surfaces for finishing and cutting slots with hand-operated grinders.
