水稳料的使用您要了解什么?

“济南水稳料”是在一些建筑材料中(碎石土,碎石等),加入一定掺量的水泥(一般来讲这个掺量没有混凝土高,在5%左右,造价也比混凝土便宜),达到一定的稳定效果。一般来讲作为建筑的基层或者路面基层使用。具有一定程度的强度和隔水效果。而且刚度不是很大,具有一定的柔性作用。
"Jinan water stabilized material" is to add a certain amount of cement into some building materials (crushed stone soil, crushed stone, etc.) (generally speaking, this amount is not as high as concrete, about 5%, and the cost is also cheaper than concrete) to achieve a certain stability effect. Generally speaking, it is used as the base course of building or pavement. It has a certain degree of strength and waterproof effect. Moreover, the stiffness is not very large and has a certain flexibility.
水稳的配合比应事先在实验室内进行配合比试配,以确定水泥掺量和粗细集料比例,同时确定大干密度。量大可采用水稳搅拌站拌合。
The mix proportion of water stabilized concrete shall be tested in the laboratory in advance to determine the cement content and the proportion of coarse and fine aggregates, as well as the large dry density. Water stabilized mixing plant can be used for mixing in large quantities.
水泥稳定碎石是以级配碎石作骨料,采用一定数量的胶凝材料和足够的灰浆体积填充骨料的空隙,按嵌挤原理摊铺压实。其压实度接近于密实度,强度主要靠碎石间的嵌挤锁结原理,同时有足够的灰浆体积来填充骨料的空隙。
Cement stabilized macadam uses graded macadam as aggregate, uses a certain amount of cementitious material and sufficient mortar volume to fill the gap of the aggregate, and paves and compacts according to the principle of inlaying. Its compactness is close to compactness, and its strength mainly depends on the principle of inlaying and locking between crushed stones, and there is enough mortar volume to fill the gap of aggregate.
它的初期强度高,并且强度随龄期而增加很快结成板体,因而具有较高的强度,抗渗度和抗冻性较好。水稳水泥用量一般为混合料3%~6%,7天的无侧限抗压强度可达1.5~4.0mpa,较其他路基材料高。水稳成活后遇雨不泥泞,表面坚实,是路面的理想基层材料。
Its initial strength is high, and its strength increases with age and quickly forms a plate, so it has high strength, good permeability and frost resistance. The dosage of cement stabilized by water is generally 3%~6% of the mixture, and the unconfined compressive strength in 7 days can reach 1.5~4.0 mpa, which is higher than other subgrade materials. After water stabilization, it is not muddy in the rain and has a solid surface. It is an ideal base material for high-grade pavement.
根据交通部《公路路面基层施工技术规范》规定,道路中采用的水泥稳定碎石均属中粒土,由于水稳中含有水泥等胶凝材料,因而要求整个施工过程要在水泥终凝前完成,并且一次达到质量标准,否则不易修整。
According to the Technical Specifications for Construction of Highway Pavement Base Course issued by the Ministry of Communications, the cement stabilized macadam used in the road belongs to medium-grained soil. Because the cement and other cementitious materials are contained in the water stabilized macadam, the whole construction process is required to be completed before the final setting of the cement and meet the quality standards at one time, otherwise it is not easy to repair.
因而施工中要求加强施工组织设计和计划管理,增加现场施工人员的紧迫感和责任感,加快施工进度,加大机械化施工程度,提高机械效率。水稳的施工方法也符合现代化大规模机械化发展的方向,因而水稳在公路工程中的应用会得到很快推广。有需求就来找我们咨询吧。
Therefore, during the construction, it is required to strengthen the construction organization design and plan management, increase the sense of urgency and responsibility of the on-site construction personnel, speed up the construction progress, increase the degree of mechanized construction, and improve the mechanical efficiency. The construction method of water stabilization is also in line with the development direction of modern large-scale mechanization, so the application of water stabilization in highway engineering will be rapidly promoted.
