The present invention relates to a process for producing a pore-containing granulate, comprising the following steps: a) producing a foamed mass using sand, hydraulic binder, foaming agent and water, b) pouring the foamed mass into a filling mould, c) partially curing the mass over a first period of time at ambient pressure to form a green block having a first target strength, and d) demoulding the green block, the process comprising the further steps e) splitting the green block into at least two sub-blocks, l) further curing the sub-blocks over a second period of time at ambient pressure until a second target strength is reached and g) breaking the sub-blocks to form pore-containing granulate with a desired particle size distribution. Furthermore, the present invention relates to a process for the production of a pore-containing artificial stone which contains the granulate as an additive.

A geo-polymeric concrete and a process for preparing the geo-polymeric concrete is disclosed. The geo-polymeric concrete includes class F fly ash in a range from 10-20 wt %, of the design mix river sand in a range from 25-40 wt % of the design mix, a natural aggregate in a range from 15 to 40 wt % of the design mix, silica fume in a range from 1 to 2 wt % of class F fly ash, an alkaline activator solution and a superplasticizer in a range from 0.5 to 3 wt %. The materials used for preparing the superplasticizer are easily available in the market in abundance at a reasonable cost. The superplasticizer is economically viable and improves the workability of the geo-polymeric concrete. The presence of the superplasticizer does not affect the compressive strength of the geo-polymeric concrete.
