Admixture for cement mortar and/or concrete
专利汇可以提供Admixture for cement mortar and/or concrete专利检索，专利查询，专利分析的服务。并且PURPOSE: To improve flexural strength, water resistance and durability of hardened material of cement and to suppress neutralization, comprising latex consisting of polymer fine particles having core.shell type different layer structure and a specific ratio of unsaturated monomer constituting the core part and the shell part.
CONSTITUTION: This admixture comprises a polymer latex consisting of polymer fine particles having a core.shell type different layer structure (multi-layer structure wherein inner part in fine particles in polymer latex fine particles is non-rigid and outer part is rigid at a specified temperature) and a weight ratio of unsaturated monomer constituting the core part and the shell part of (90/10)-(10/90) as an essential component. When the weight ratio of unsaturated monomer exceeds 90/10, compression strength, flexural strength and water reducing effects are not sufficiently shown because of destruction of the different layer structure and when the weight ratio of unsaturated monomer，下面是Admixture for cement mortar and/or concrete专利的具体信息内容。
