轻质混凝土
摘要：
本发明公开了一种轻质混凝土，属于建筑材料领域。包括硅酸盐水泥、骨料、粉煤灰、钢渣、酸性纸浆废液、聚丙烯短纤维和高效超塑化剂，所述硅酸盐水泥、骨料、粉煤灰、钢渣的质量比为10:(5‑6):(3‑5):(1‑2)；所述酸性纸浆废液与硅酸盐水泥的质量比1:(10‑11)，酸性纸浆废液与高效超塑化剂的质量比为(10‑11):1。纸浆废液运用于混凝土的制作工艺中，可以有效的变废为宝，并且酸性的纸浆废液可以促进泡沫混凝土的发泡体积，进一步降低混凝土的质量；再者粉煤灰、钢渣具有较大的比表面可以提高混凝土基材的抗压强度；在泡沫混凝土中加入聚丙烯短纤维可以阻止混凝土裂缝的产生，延长使用寿命，同时提高抗震性能。
摘要（英）：

The invention discloses a light-weight concrete, belonging to the field of building materials. The light-weight concrete is prepared from Portland cement, aggregate, fly ash, steel slag, acidic pulp waste liquor, polypropylene staple fibers and a high-efficiency superplasticizer, wherein the mass ratio of the Portland cement, aggregate, fly ash and steel slag is 10:(5-6):(3-5):(1-2); the mass ratio of the acidic pulp waste liquor and Portland cement is 1:(10-11); and mass ratio of the acidic pulp waste liquor and high-efficiency superplasticizer is (10-11):1. When the pulp waste liquor is used in the concrete manufacturing technique, the waste can be effectively changed into the valuable substance, and the acidic pulp waste liquor can promote the foam volume of the foamed concrete, thereby further lowering the concrete weight. The fly ash and steel slag have larger specific surfaces, and thus, can enhance the compression strength of the concrete base. The polypropylene staple fibers added into the foamed concrete can prevent the concrete cracks from generation, thereby prolonging the service life and enhancing the earthquake resistance.
