What Makes Concrete a Sustainable Building Material?

Pervious concrete is a special type of structural concrete with a sponge-like network of voids that water passes through readily. When used for driveways, sidewalks, parking lots, and other pavements, pervious concrete can help to retain stormwater runoff and replenish local water supplies. Minimal waste.

Concrete The Basic Mix

iii. rodding the concrete inside the mold with a thin spatula. Special chemicals called water reducing agents are used to improve workability at low water to cement ratios and thus produce higher strengths. Most ready-mix companies use these chemicals, which are known commercially as superplasticizers.

Sand and Gravel in Concrete Shelly Company

Jan 30, 2014Sand and Gravel in Concrete. The strength of the concrete is inversely proportional to the water/cement ratio. In other words, the more water you use to mix the concrete, the weaker the concrete mix. The less water you use to mix the concrete, the stronger the concrete mix. A mix with little water and more concrete mix will be dryer and less workable but stronger.

Why does concrete heat up while it's drying? Isn't it just

Cement is the key to making concrete. Otherwise you'd just have a pile of wet rocks and sand. Contrary to popular belief, concrete doesn't dry. The water actually reacts with cement and the two produce something altogether different. It doesn't dry because the water is evaporating; it dries because the water is becoming part of the concrete.
