通过优化混凝土的原材料及配合比，采用中强低弹粗骨料及高胶材用量等措施，使配制的混凝土２８ｄ抗压强度达９．５ＭＰａ，弹性模量为８８０ＭＰａ，弹强比为９３，渗透系数为３．８×１０－１１ｍ／ｓ，后期强度增长率大，其相应龄期弹强比可降低６０％以上，自身体积变形具有微膨胀性，有较大的应力—应变特性。这种具有中强、低弹及自密性好的塑性混凝土，可用于高中土石坝的永久性防渗墙。该混凝土的原材料来源广、价格低、施工简便、质量稳定，具有推广应用价值。
By optimizing the raw materials and mix ratio of concrete, using the medium and low elastic coarse aggregate and high amount of plastic materials and other measures, the prepared concrete 28d compressive strength of 9.5MPa, elastic modulus of 880MPa, elastic ratio of 93, The permeability coefficient is 3.8 × 10-11m / s, and the late strength growth rate is large. The elastic-to-concrete strength ratio at the corresponding age can be reduced by more than 60%. The deformation of the volume has micro-expansibility and large stress-strain characteristics. This kind of plastic concrete with medium strength, low elasticity and self-density can be used as a permanent impervious wall for high school earth-rock dam. The concrete raw materials from a wide range of sources, low prices, construction is simple, stable quality, with the promotion and application value.
