EPiC database - Concrete 20 MPa

This material is part of the free Environmental Performance in Construction (EPiC) Database. The EPiC Database contains embodied environmental flow coefficients for 250+ construction materials using a comprehensive hybrid life cycle inventory approach.Concrete is a composite material combining sand or other fine aggregates, coarse aggregates, a binder and water. Portland cement is the most commonly used binder, however other binders, such as polymers, may also be used. Supplementary Cementitious Materials (SCM) such as Fly Ash and Ground, Granulated Blast Furnace Slag (GGBFS), are also commonly used as a part replacement for Portland cement. Additives, such as plasticisers can be added to the mix to control concrete properties, such as workability. Concrete is usually combined with steel reinforcement to improve tensile strength.Concrete is one of the most commonly used construction materials. It is highly durable and is thus typically used for structural elements in buildings and infrastructure projects. Concrete can be manufactured to meet a variety of strength grades. Concrete 20 MPa is commonly used in domestic floor construction, garage floors and driveways, where the loads supported are lighter. The typical mix ratio is 1:1.5:3 (cement, sand, coarse aggregate).

本资料属于免费的环境绩效在建筑（EPiC）数据库的一部分。EPiC数据库包含了超过250种建筑材料的环境负荷流动系数，这些数据采用了一种综合的混合生命周期清单方法进行计算。混凝土是一种复合材料，它由砂或其他细骨料、粗骨料、粘结剂和水组成。波特兰水泥是最常用的粘结剂，然而，其他粘结剂，如聚合物，也可能被使用。补充性胶凝材料（SCM），如飞灰和磨细高炉矿渣（GGBFS），也常被用作波特兰水泥的部分替代品。为了控制混凝土的性质，如工作性，混合物中可以添加添加剂，例如塑化剂。混凝土通常与钢筋结合使用，以提高抗拉强度。混凝土是使用最广泛的建筑材料之一。它具有极高的耐久性，因此通常用于建筑和基础设施项目的结构元素。混凝土可以被制造以符合各种强度等级。20 MPa的混凝土常用于国内楼板建设、车库楼板和车道，这些地方的承重较轻。典型的配合比为1:1.5:3（水泥、砂、粗骨料）。
