EPiC database - Concrete 50 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 50 MPa is commonly used in commercial and civil construction where high strength and durability are required. The mix will generally have a lower water to cement ratio than standard concrete.

本材料属于免费环境性能在建筑（EPiC）数据库的一部分。EPiC数据库包含利用全面混合生命周期清单方法，对250多种建筑材料进行的环境流系数的内在化分析。混凝土是一种复合材料，由砂或其他细骨料、粗骨料、粘合剂和水组成。波特兰水泥是最常用的粘合剂，然而，其他粘合剂，如聚合物，也可使用。补充水泥材料（SCM），例如粉煤灰和细磨高炉矿渣（GGBFS），也常作为波特兰水泥的部分替代品。混合料中可添加添加剂，如塑化剂，以调控混凝土的特性，如工作性。混凝土通常与钢筋结合使用，以增强其抗拉强度。混凝土是应用最为广泛的建筑材料之一，其耐久性极高，因此常被用于建筑和基础设施项目的结构构件。混凝土可按多种强度等级制造。50 MPa的混凝土常用于商业和民用建筑，因其需满足高强度和耐久性的要求。该混合料的用水量与水泥的比例通常低于标准混凝土。
