为了扩大松香用途,提高经济效益,1982年8月,我们开始了以松香为主要原料的凝胶材料(水泥)加气剂的研制。成样后经县建筑材料试验站测试及房产局施工队的实际使用,证明本剂符合建筑施工要求,能改善混凝土和砂浆多种物理力学性能,节省原材料,减轻劳动强度,降低工程造价。目前,除本县建筑队使用外,恩平、阳江、阳春及广州的一些建筑单位也开始试用.RBN——A是以加气为主的多功能的混凝土、水泥砂浆外加剂,对水泥活性成份具有良好的强化作用。其主要原理是经充分搅拌后,在混凝土或水泥砂浆内部产生很多极细小的气泡微沫,减弱了骨科间的接触磨擦
In order to expand the use of rosin and improve economic efficiency, in August 1982, we started the research and development of gel material (cement) air-entraining agent with rosin as the main raw material. After the sample test by the County Building Materials Test Station and the actual use of the real estate team construction team proved that the agent meets the requirements of construction, can improve a variety of physical and mechanical properties of concrete and mortar, saving raw materials, reduce labor intensity and reduce project cost. At present, in addition to the use of the county’s construction team, a number of construction units in Enping, Yangjiang, Yangchun and Guangzhou have also begun trial use.RBN-A is a multifunctional concrete and cement mortar admixture mainly based on aeration, Ingredients have a good strengthening effect. The main principle is that after sufficient mixing, a lot of very fine bubbles in the concrete or cement mortar weaken the contact friction between the orthopedics
