甘肃省第一建工局建筑科学研究所正在研究通过强化作用,提高粉煤灰硅酸盐制品的强度。从而,在普通常压蒸汽养护条件下,生产粉煤灰加气混凝土承重砌块。强化作用的工作原理:将粉煤灰、石灰、石膏等原料混合加水,经高速搅拌制成料浆。将搅拌后料浆再通过泥浆泵加压,送入强化喷头,料浆以高速从喷头喷出。这样反复喷射数次,对料浆进行了强化处理(有的认为是超声作用,也有的认为是无介质磨细
The Building Research Institute of the First Construction and Construction Bureau of Gansu Province is studying the enhancement of the strength of fly ash silicate products. As a result, fly ash aerated concrete bearing blocks are produced under normal pressure steam curing conditions. Strengthen the working principle: the fly ash, lime, gypsum and other raw materials mixed with water, made of high-speed mixing slurry. After stirring, the slurry is pressurized by a mud pump and fed into a fortified nozzle, and the slurry is ejected from the nozzle at a high speed. In this way, the slurry was repeatedly sprayed several times, and the slurry was strengthened (some of them were considered to be ultrasonic and some were considered to be no medium.
