STABILIZATION OF SAND WITH CEMENT AT LOW TEMPERATURES

STABILISEREN VAN ZAND MET CEMENT BIJ LAGE TEMPERATUREN

It was investigated whether the production of sand cement is possible and justified in periods when frost occurs, more particularly during the night and in the early morning, while the day time temperature level keeps the average 24 hours temperature a few degrees celsius above zero. Furthermore it was investigated whether supplementary arrangements on the site of the stabilization work are needed in order to ensure that a sand cement stabilized layer of good quality is obtained. The investigations relating to keeping the sand bed free from frost were based on a precaution already commonly applied in practice, namely, the addition of calcium chloride to the sand. The effect of calcium chloride in this sand upon the formation of solid frozen zones was studied. Furthermore, the various methods of introducing the salt into the sand bed were investigated. The laboratory and field tests concerned are described. The effect of low temperature and of the presence of calcium chloride on the quality of the sand cement was the subject of a number of laboratory investigations. Within the framework of practical research some tests were carried out on roads under construction. The effect of this salt and of covering the stabilized sand bed upon the quality of the sand cement was studied. /TRRL/
