混凝土早期开裂因素的初探
Basic discussions on early-age cracking factors for concrete
【摘要】 本文采用板状开裂架对不同水胶比的混凝土1天~3天龄期的开裂行为进行了研究。探讨了养护条件、混凝土工作性能、砂率以及砂的细度模数等因素对混凝土早期开裂的影响,并提出了减少、避免开裂的相应措施。
【Abstract】 Plate specimen was adopted to investigate restrained shrinkage cracking of concrete in order to ensure the durability of concrete and decrease the quarrel in engineering.The factors which affect early age cracking were studied such as curing methods,workability,sand ratio and modulus of sand.Corresponding solutions were put forward.
