CM-A混凝土薄膜养护剂是石蜡乳状液类新型养护剂,水分损失量力0.039克/厘米~2[ASTMC156-74]。CM-A具有良好的保水性能,能够防止混凝土的干缩。养护混凝土试件的抗压、抗拉强度与湿麻袋复盖养护的相当或略高一些。对于连续砌筑或分层浇注的混凝土层面。去膜可与刷毛同时进行。采用刷毛处理的外力,已足够除去养护膜层,不会影响新老混凝土的结合。CM-A在大坝、港口、市政工程的应用中都取得了较好的养护效果,具有明显的经济效益。国家专利局已经受理该项研究成果的专利权申请。
CM-A concrete film curing agent is a new type of paraffin emulsion curing agent, moisture loss of 0.039 g / cm ~ 2 [ASTMC156-74]. CM-A has a good water retention, to prevent concrete shrinkage. Conservative concrete specimen compression, tensile strength and wet sacks cover conservation quite a bit or slightly higher. For continuous masonry or layered concrete floor. To the film can be carried out with the bristles. The use of bristles to handle the external force has been sufficient to remove the protective film, will not affect the combination of old and new concrete. CM-A has achieved good curing effect in the application of dams, ports and municipal engineering, with obvious economic benefits. National Patent Office has accepted the patent application for the research results.
