Effect of dispersed mineral additive on properties of mortar mixture and solution

[摘要] The results of dispersed mineral (limestone) and plasticizing additives effect on the properties of the solution mixture and solution are presented in the articles. It is shown that the introduction of a dispersed mineral additive has a significant effect on water-retaining capacity of mortar mixture, mortar hardening and increasing its water resistance. The optimal amount of the additive, based on the maximum values of the investigated indicators, is 7 - 9%. The solution strength increases to 15%. It is shown that, when the limestone and hydrated lime are added, the water-retaining capacity of the solution mixture increases up to 90%. The introduction of 7% of the dispersed mineral additive makes it possible to obtain a water-resistant solution with 25% hydrated lime.
