Additive for increasing strength of cement developed
The additive developed by the new technology study and dissemination office under the commission can increase the compression strength of general cement more than 1.2 times when the additive equivalent to 0.3 percent of the amount of cement is added. Therefore, it is possible to improve the quality of construction and save a lot of cement.
The additive, whose effectiveness was proved through a number of tests, is now in wide use at the construction sites.
