Development of lightweight aggregate concrete

Figure 1. Comparison of concrete weights. Natural lightweight aggregates were durable enough in early concrete, but when combined with portland cement in the early 1800s, they could not provide the necessary strength. About 100 years later, a way to make strong, lightweight aggregate was discovered by heating shale, clay and slate until they ...

Early-Age Behavior of Lightweight Aggregate Concrete

lightweight aggregates in concrete can reduce or eliminate the stress development caused by autogenous shrinkage. The decrease in autogenous stresses is due to internal curing, because water desorbed from the lightweight aggregates fills capillary voids formed by chemical shrinkage. The B3 Model is a compliance model that was designed and
