Influence of crusher type in the shape of fine crushed aggregate grains Open
Quarries have invested in equipment to increase production and improve the quality of their products, such as vertical shaft impact crushers (VSI). This type of crusher works with autogenous comminution of the material to improve the shape…
View article: Influence of cement type and water content on the fresh state properties of ready mix mortar
Influence of cement type and water content on the fresh state properties of ready mix mortar Open
The main characteristic of ready mix mortar is to remain workable for up to 72hours after mixing. This greater duration of workability is obtained by use of hydration stabilizing admixtures and air-entrained admixtures. Thus, the behavior …
