Experiments indicate that Ca(OH)2 [CH] aggravates alkali-silica reaction causing increased expanslon of mortar bars. Ca(OH) 2 has two major functions: firstly it acts a "buffer" to maintain a high pH, i.e. a high concentration of hydroxyl ions in pore solutions; secondly, Ca++ ions may exchange for

The presence of chlorides promotes a positive electrokinetic charge of silica. Silica shows an isoelectric point (iep) at pH 2 in the presence of HCl but at pH < 1.5, if any, in the presence of HClO 4 and HNO 3 . The iep of silica in the presence of different 1:1 salts depends on the nature and conc
The hydrodynamics and statics of wet colloidal systems depend on the solution salt type and solution concentrations with which they are in equilibrium. The management of these systems therefore requires some understanding of the consequences of hydrodynamic dispersion and chemical reaction that may
