由于平原地区砂卵砾石层孔隙度大，故地下水丰富，总储量超过140亿立方米，以埋藏浅、变幅小、水量稳定、开采方便、矿化度低、水质好为特点。

Pore structure experiment shows that porosity of high volume fine mineral mixture RPC is about 5%, the pore distribution is uniform and the main pore is small. When the cement content of high volume fine mineral mixture RFC is 300 kg/m^3, its sclerotium hydration products is dense packed by irregular equal Ⅲ style C-S-H gels. The gels are fine, dense, and integrate with the aggregate.
