lightweight aggregate production

Lightweight Aggregate Production Process

Production Process The raw material is processed by heating in rotary kilns at temperatures in excess of 2000° F under carefully controlled conditions. The result is a structural grade ceramic lightweight aggregate that is screened to produce precise gradings required for use in asphalt surface treatments, structural lightweight

11.20 Lightweight Aggregate Manufacturing

Lightweight aggregate is a type of coarse aggregate that is used in the production of lightweight concrete products such as concrete block, structural concrete, and pavement. The Standard Industrial Classification (SIC) code for lightweight aggregate manufacturing is 3295; there currently is no Source Classification Code (SCC) for the industry.

LIGHTWEIGHT AGGREGATES: A FEASIBLE OPTION FOR ALASKA?

pyroplastic mass. “Strong, durable lightweight aggregates are produced when small-size, well-distributed, noninterconnected pores are enveloped in a continuous, crack free, vitreous phase” (Holm, 1995). The pore spaces are the key to the low unit weight of lightweight aggregates. Houston et al. (1969) studied the effect of temperature and

Pre-soaking Lightweight Aggregate for Pumped Concrete

What are the best methods for pre-soaking lightweight aggregate for concrete that will be pumped? Concrete containing lightweight aggregate can experience severe slump loss during pumping if the aggregate isn't wet enough. Because of this, some producers of lightweight aggregate use vacuum or thermal processes to saturate their material.
