Municipal road well lid periphery quick-hardening anti-seepage fine aggregate concrete
The invention provides municipal road well lid periphery quick-hardening anti-seepage fine aggregate concrete which comprises the following raw materials: sulphoaluminate cement, Portland cement, quartz sand, calcium chloride, lithium carbonate, hydroxypropyl methyl cellulose, a polycarboxylate superplasticizer, melon stone, sand and water.Compared with the prior art, the municipal road well lid periphery quick-hardening anti-seepage fine aggregate concrete has the following beneficial effects that high strength can be achieved within a short time, and the service life of the municipal road well lid periphery quick-hardening anti-seepage fine aggregate concrete is prolonged; the construction efficiency is obviously improved, and the road closing time is shortened; meanwhile, the anti-permeability and durability are enhanced, the service life is prolonged, the municipal maintenance cost is reduced, the fiber reinforcing agent is added to achieve the reinforcing and anti-cracking effects, and the fiber reinforcing agent is distributed in the concrete in a random or directional mode. After the concrete is hardened, the fibers exist in a concrete matrix in a multidirectional staggered manner to form a continuous three-dimensional network. Due to the distribution characteristic, the fibers form a bridging effect in the concrete, and the overall structural strength of the concrete is improved.
本发明提供一种市政路井盖周边快硬抗渗细石混凝土，包括以下原料：硫铝酸盐水泥，硅酸盐水泥，石英砂，氯化钙，碳酸锂，羟丙基甲基纤维素，聚羧酸减水剂，瓜米石，砂，水，与现有技术相比，本发明具有如下的有益效果：在短时间内即可实现高强度，显著提高施工效率，减少道路封闭时间；同时，增强的抗渗和耐久性，延长了使用寿命，减少了市政维护成本，纤维增强剂的添加起到增强和抗裂的作用，在混凝土中，纤维增强剂以随机或定向方式分布。当混凝土硬化后，这些纤维会以多方向交错的形式存在于混凝土基体中，形成一个连续的三维网络。这种分布特性使得纤维在混凝土内部形成“桥接”效果，增加了混凝土的整体结构强度。
