Possibilities of Waste Raw Materials Application in Grouting Materials

conference paper

English

Repeated problem in foundation engineering is the unstable subsoil with low bearing capacity. The stabilization of geological subsoil by grouting mixtures, in places where the original subsoil does not have the demanded bearing capacity is a technology known already for more decades. It concerns the pumping process of liquid with changeable viscosity into the soil, into disintegrated soil or concrete with the aim to decrease the permeability. Clay-cement or purely cement suspensions were formerly used for this purpose. However this methods do not meet sufficiently the requirements of today is building industry. The endeavour or trend of the last years is the utilization of economically not demanding waste materials. This is the advantageous utilization of these materials exactly into grouting mixtures for the stabilization of subsoil or for filling of bulk caverns.
