This is available from the website or your local Parchem branch. Pumping Where large volumes have to be placed Conbextra C may be pumped. A heavy duty diaphragm pump is recommended for this purpose. Screw feed and piston pumps may also be suitable. Maximum aggregate size for pumping is 0.3 mm. Ensure the selected pump is capable of pumping this size aggregate. Curing On completion of the grouting operation, exposed areas should be thoroughly cured. This should be done by the use of Concure curing membrane and continuous application of water and/or wet hessian. Cleaning Conbextra C should be removed from tools and equipment with clean water immediately after use. Cured material can be removed mechanically. Limitations Low temperature working When the air or contact surface temperatures are 5°C or below on a falling thermometer, warm water (30 - 40°C) is recommended to accelerate strength development. For ambient temperatures below 10°C the formwork should be kept in place for at least 36 hours. Normal precautions for winter working with cementitious materials should then be adopted. High temperature working At ambient temperatures above 35°C cool water (below 20°C) should be used for mixing the grout prior to placement.
