From an extensive petrographic investigation of concrete samples suffering from alkali-silica reaction, it has been hypothesized that a deliberately introduced air-bubble system will reduce expansion due to alkali-silica reaction. The above hypothesis has been tested using mortar bars made from 35 s

It has been shown that expansion of mortar prisms, due to alkali-silica reaction, can be quantitatively related to their environment, i.e. alkali ion concentration and temperature by an equation of the type The physical significance of negative signs of dl/dC and dl/dT terms have been discussed.

Recently a method for the detection of alkali-silica reactivity of sand has been proposed. In this method sand is digested in a mixture of Ca(OH)2 and saturated KCl for 24 hours. The OH ion concentration is determined by titration. The OH ion concentration for a control mixture without sand is deter

The effect of LiNOz on the expansion of mortars made completely of reactive aggregate with five particle size fractions was investigated by means of an autoclave test. The results show that the effect of LiNOz varies with its content and NazO level, or more specifically, with the molar ratio of Li/N

The use of superplasticizers (SP) is widespread in today's concrete production. Usually, SP are used when specific demands in regard to workability, strength or durability have to be met. As they contain sodium sulphate, they have the potential to increase the alkalinity in the pore solution and the
