抗压强度是衡量混凝土质量的重要指标,而新拌混凝土水灰比是决定抗压强度的关键。因此,国内外许多研究者在研究快速测强的同时,都致力于研究水灰比的快测方法,以谋求在更短的时间内从实测的水灰比推定混凝土28天强度,判定混凝土的质量。对于水灰比的测定,国内外曾提出很多方法,如比重法、容积法、水洗筛分法、溶解热法、逆
Compressive strength is an important indicator to measure the quality of concrete, and the water-cement ratio of fresh concrete is the key to determining compressive strength. Therefore, many researchers at home and abroad are researching rapid strength measurement and are all devoted to the study of water-cement ratio rapid measurement methods to seek to determine the strength of concrete in 28 days from the measured water-cement ratio in a shorter time. quality. For the determination of water-cement ratio, many methods have been proposed at home and abroad, such as specific gravity method, volumetric method, water-washing sieving method, solution heat method, and inverse method.
