山东省在历城、泰安、莱阳三个试点将石灰烧粘土水泥,进行了示范施工.水泥的标号是75-100号,从砌石180立方公尺,抹面165平方公尺,抅缝178立方公尺来看施工效果良好,通过示范施工,不仅树立了石灰烧粘土水泥的威信,而且解决了农业社的需要和节约了资金.例如泰安桃园一座高14公尺长40公尺的拦洪坝,原设计内部用石灰砂浆砌筑,外部用400号水泥砂浆砌筑,改用石灰烧粘土水泥代替石灰,和部分高标号水泥,不仅保证了工程质量,还降低工程造价8千余元.又如胡家乡处于山麓,用水非常困难,全村400多个旱井过去都用灰泥抹面,漏水现象严重,这次用石灰烧粘土水泥拌成混凝土打底及砂浆抹面,经过灌水试验完全不漏水,还节约了工料.因此农民非常欢迎低标号水泥.
Shandong Province, Licheng, Tai’an, and Laiyang will conduct lime cement and cement demonstration at three experimental sites. The cements are numbered 75-100, from stone masonry 180 cubic meters, plastered surface 165 square meters, and quilted 178 cubic meters. From the perspective of the meter, the construction works well. Through demonstration construction, it not only established the prestige of lime-fired clay cement, but also solved the needs of the agricultural community and saved funds. For example, a dam 14 meters high and 40 meters high in Tai’an Taoyuan The original design was built internally with lime mortar, externally made with 400-gauge cement mortar, replaced with lime-fired clay cement instead of lime, and some high-grade cement not only ensured the project quality, but also reduced the construction cost by more than 8,000 yuan. If Hu Jiaxiang is in the foothills, it is very difficult to use water. Over 400 dry wells in the village have been plastered in the past. The water leakage phenomenon is serious. This time, lime-fired clay cement is mixed with concrete to make a base and mortar is used to plaster the surface. After the irrigation test, no water leakage occurs. It also saves the amount of material. Therefore, the peasants very much welcome the low-grade cement.
