Fundamentals of Concrete

The batch plant operator measures the aggregate moisture and finds that the fine aggregate moisture is at 5%. The coarse aggregate, just delivered, has a moisture content of 0.5%. The operator computes the add-water as follows: Fine aggregate = 1100 lbs x (0.05 – 0.02) = + 33 lbs Coarse aggregate = 2021 lbs x (0.005 – 0.01) = - 10 lbs

Aggregate Heating, Sand Heating — Steam Engineering

As a rule of thumb, one million BTU can heat 40 tons of sand to 125F in one hour. When left out-side, this sand would only lose 10F to 15F per day. With your sand heated to 125F, you no longer need to superheat water. Still, however, Steam Engineering technology allows you to heat water to 140F very efficiently, at a rate of 1,200

Aggregates

Aggregates. There are two main classes of aggregates: natural and manufactured. Natural aggregates come from sand and gravel deposits. These formations often contain materials like clays and silts that must be thoroughly processed out before using the sand and gravel in commercial applications. Manufactured aggregates are obtained from deposits
