Abstract: This paper describes the use of a new emulsion/microencapsulation of a silicone resin as an integral water repellent for cement-based matrix and fibre reinforced cement boards. The impact of the new emulsion as a hydrophobic admixture in mortar on water uptake, cement setting time and mechanical properties is given. The impact of adding this emulsion/microencapsulation of silicone resin in mortar or lab made fibre reinforced cement board composition is illustrated. Impact on the water uptake and efflorescence of the modified material was evaluated. The mechanism which can explain the retention of the emulsion into the FRC boards is suggested.
