How to calculate the weight of cement in cement slurry with water cement ratio of 1: 1 (weight ratio)

2: The unit cement content of1mud is 0.43 1kg, and the cement weight in 1 m3 cement slurry is 43 1kg. The specific gravity of cement is calculated as 3. 1. The calculation method is 1/(2+ 1/3. 1)=0.43 1kg, 1 m3 cement quantity: 0.431*1000 = 431kg.

The cement slurry of 1: 1 is the weight ratio. If the dry density of cement is 0/600 kg per cubic meter/kloc (this specific gravity cannot be used for accurate calculation, and the laboratory should calculate the density of cement first according to different types of cement), the formula is V= 1/2.6, and the volume of cement in a cubic meter of cement slurry is 0.3846, and the weight is 0.3846 *1600 = 6650. This weight also increases the cement loss by 2%.

1. The water for preparing cement slurry can be fresh water or salt water (including seawater).

2. Cement used to prepare cement slurry is made of limestone and clay by calcination, cooling and grinding at 1450~ 1650 degrees Celsius, and mainly contains the following silicates and aluminates:

( 1)? Tricalcium silicate: The content of tricalcium silicate is the highest in cement, and its hydration rate, strength growth rate and final strength are very high.

(2)? Dicalcium silicate: In cement, the content of Dicalcium silicate is less than that of Tricalcium silicate. Although its hydration rate and strength growth rate are low, its final strength is high.

(3)? Tricalcium aluminate: the content of tricalcium aluminate in cement is less. Although its hydration rate is high, its strength increase rate is low and its final strength is low.
