Lime Concrete – Mix Proportions, Uses and Properties
Lime concrete is composite mixture of lime as binding material, sand as fine aggregate and gravel as coarse aggregate in appropriate proportions. Lime concrete mix ratio depends on the type of construction, but in general, it can be taken up to 1:2 ratio for lime, sand respectively and up to 1:3 ratio for lime, coarse aggregate respectively.
Digging Into The World Of Sand
We can use that stuff for concrete, which is the number one thing that we use sand for by far– is concrete. For concrete, you don't need sand that's especially pure– in other words, that has a super high quartz content. The next step up is sand that you use for glass making. And for that, you need sand that's much higher purity.
