Abstract
Concrete prism tests have been carried out to test the effectiveness of lithium compounds in reducing the expansion of concrete due to alkali silica reaction. Calcined flint cristobalite was used as the reactive aggregate in concrete mixes with material proportions close to those of field concretes. With respect to the quantity of lithium required to alleviate asr in a given mix the results are broadly in agreement with those published by other laboratories using other reactive aggregates. The work also showed that adding only half the necessary quantity of lithium to a concrete mix does little or nothing to reduce asr expansion, so that full measures of lithium compounds need always to be used wherever the addition of lithium for this purpose is considered desirable. The supply and cost of lithium compounds are also briefly discussed in this report.
