Sufficient grout must be available prior to starting and the time taken to pour a batch must be regulated to the time taken to prepare the next one. Continual grout pour must be ensured. The mixed grout should be poured only from one side of the void to eliminate the entrapment of air or surplus pre-soaking water. This is best achieved by pouring the grout across the shortest distance of travel. The grout head must be maintained at all times so that a continuous grout front is achieved. Please refer to the Conbextra Cementitous Grouts Application Guide for further information. This is available from the website or your local Parchem branch. Pumping Where large volumes have to be placed Conbextra HF may be pumped. A heavy duty diaphragm pump is recommended for this purpose. Screw feed and piston pumps may also be suitable. Maximum aggregate is 2.5 mm. Ensure 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 WB curing membrane, continuous application of water and/or wet hessian. Cleaning Conbextra HF 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 10oC the grout consistency should be flowable and the formwork should be maintained 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 the mixed grout should be stored in the shade. Cool water (below 20°C) should be used for mixing the grout. Estimating Supply 201050 - Conbextra HF is supplied in 20 kg moisture resistant bags. Yield Consistency (AS 1478.2-2005 Table 220.127.116.11) Yield (Litres of mixed material) Stiff 10.4 Plastic 10.7 Flowable 10.8 Fluid 10.9 Storage Conbextra HF has a shelf life of 12 months if kept in a dry store in sealed bags. If stored in high temperature and high humidity locations the shelf life may be reduced.
