玻化微珠保温砂浆施工养护问题

时间:2016-07-18     作者:www.hdbwsj.com【原创】   阅读

水泥基预拌玻化微珠保温砂浆在抹灰、砌筑工程及地面工程中应用时,需对其进行养护以达到要求的强度。

Cement base ready-mixed vitrified beads insulation mortar in plaster, masonry engineering application and ground engineering, the need for maintenance in order to achieve the strength of the requirements.


在商品化玻化微珠保温砂浆的养护过程中,水泥水化需一定的温湿条件,而商品化玻化微珠保温砂浆中所掺加的聚合物外加剂是通过失水凝聚成膜的,需要干燥的环境,所以水化凝结与聚合物凝聚成膜过程相互矛盾。因此,对商品化的玻化微珠保温砂浆的养护,必须既满足水泥充分水化,又要保证聚合物能干燥凝聚成膜,从而满足商品化的玻化微珠保温砂浆抗压、抗裂、耐久性等要求。

In the curing process of commercialization vitrified beads insulation mortar, cement hydration needs certain humidity conditions, and the commercialization of vitrified beads in the thermal insulation mortar mixed with polymer additive is through condensation of water into the membrane, need a dry environment, so the hydration condensation and condensation polymer film-forming process contradict each other. Therefore, the commercialization of vitrified beads insulation mortar of maintenance, must satisfy the cement hydration fully, and to ensure that the polymer can condense into dry, so as to meet the commercialization of vitrified beads insulation mortar compressive strength, crack resistance, durability and other requirements.
