　　随着材料科学的不断发展，混凝土的用途也越来越广泛，是跨行业、跨学科、互相渗透的非常广泛的领域。水泥混凝土由于具有强度高、原材料储量大、可塑性能优异、成本低廉等特点，在土木工程中起着极其重要的作用，是现代应用最广泛的建筑材料。它是由水泥、砂、石、添加剂、外加剂和适量水混合逐渐硬化形成的人工石材。混凝土的强度是指混凝土受力达到破坏极限时的应力值及结构中混凝土是否达到的“期望强度”。本文现就如今工程中常用的混凝土强度检验的方法作如下分析。

With the development of material science, the use of concrete is more and more widely, is a cross-sectoral, inter-disciplinary, each other very wide areas. Cement concrete has the characteristics of high strength, large reserves, plastic raw materials with excel ent performance and low cost, plays a ve-ry important role in civil engineering, is the most widely used modern building materials. It is made of cement, sand, stone, additives, admixture and a moderate amount of water mixed g-radual y harden to form the artificial stone. The strength of the concrete means to achieve the desired strength of concrete is the “stress and structural failure limit the stress of concrete”. In this paper, we wil analyze the test method of concrete stren-gth now usual y used in engineering as fol ows.
