干好了混合
这是一种典型的混合在许多家装商店发现。它装在一个袋子里，包含了混凝土的所有必要成分，除了水。它清楚地表明，当加水时，干燥的混凝土混合物将产生大量的混凝土，这使得计算项目需要多少很容易。一些制造商为不同类型的项目提供几种类型。要使用所有你需要的是适当的水和一个地方和工具来搅拌混凝土。如果你按照制造商的说明，这种类型的混凝土几乎是万无一失的。然而，您将支付更多的干燥准备混合比其他类型的混合。对于小的工作，干燥的混合物实际上比其他选择更经济，所以如果经济是优先考虑的，不要自动排除这个选择。然而，对于大型项目来说，另一种选择几乎总是更便宜。速配速配是另一种产品，适合于随意的自己动手，尽管它比干的速配更难找到。 This option comes with water added, ready to be immediately used.
