在本文中，提出了水泥基材料包括灌浆、普通混凝土、陶粒混凝土和泡沫混凝土标准养护28天抗压强度的水灰密度比定律。测试了不同灌浆材料、普通混凝土、陶粒混凝土和泡沫混凝土的标准养护28天抗压强度。对艾布拉姆斯定律、波洛米公式和水灰密度比定律进行了模拟和比较。水灰密度比规律较好地模拟了水泥基材料28天抗压强度的预测。水灰密度比规律包括水灰比和水泥基材料的相对表观密度。水泥基材料的相对表观密度是决定水泥基材料抗压强度的重要因素之一。水灰密度比规律有利于水泥基材料28天标准养护抗压强度的准确、通用预测。
In the present contribution, the water-cement-density ratio law for the standard curing 28-day compressive strength of cement-based materials including grout, normal concrete, ceramsite concrete, and foamed concrete is proposed. The standard curing 28-day compressive strength of different grouts, normal concrete, ceramsite concrete, and foamed concrete was tested. Simulations for Abrams’ law, Bolomey’s formula, and water-cement-density ratio law were carried out and compared. The water-cement-density ratio law illustrates better simulations for the prediction of the 28-day compressive strength of cement-based materials. The water-cement-density ratio law includes both the water-cement ratio and relative apparent density of the cement-based material. Relative apparent density of the cement-based material is an important one of all the factors determining the compressive strength of the cement-based material. The water-cement-density ratio law will be beneficial for the precise and generalized prediction of the 28-day standard curing compressive strength of cement-based materials.
