一般的水工建筑物,如拱坝、隧洞、闸、涵、溢洪道、灌渠等的混凝土,由于要经常的或是周期性的与水接触,故有强度与耐蚀的要求.有些混凝土建筑物体积较大,易由于水泥的水化热不易发散等原因而产生裂缝.因此对水工建筑物所用的混凝土技术要求与普通工业、民用建筑物的混凝土不完全一样.除一般要求的抗压强度外;还得有一些其他的特殊要求,如抗冻性、抗渗性、抗拉强度、抗磨性、低热性、抗浸蚀性等.如
General hydraulic structures, such as concrete arch dam, tunnel, gate, culvert, spillway, irrigation canal and other concrete, because of regular or periodic contact with water, it has the strength and corrosion resistance.Some concrete buildings Large size, easily due to the hydration of cement is not easy to diverge and other reasons, cracks, so for hydraulic structures used in concrete technology requirements and ordinary industrial, civil buildings, concrete is not exactly the same.In addition to the general requirements of compressive strength Outside; There are some other special requirements, such as frost resistance, impermeability, tensile strength, abrasion resistance, low heat, corrosion resistance, etc.
