WITHOUT CLINKER BINDERS BASED ON HIGHLY DESCRIBED SAPONIT-CONTAINING WASTE OF THE DIAMOND-MINING INDUSTRY
Abstract
The results of experimental research of hydration process of highly dispersed systems based on saponit-containing waste, extracted as the solid phase of the recycled water suspension kimberlite ore enrichment process of the diamond industry. Saponitcontaining sludge was dehydrated and subjected to mechanical activation on the planetary ball mill. Mechanical activation of raw material more than 60 minutes does not increase the specific surface area of samples was found. Specific surface area is achieves the maximum value of 50600 m2/kg. If we increasing the time of mechanical dispergation up to 120 minutes this parameter will be decrease due to agglomeration of particles. At the same time, average particle size of saponit-containing material will be in ranges from 445 to 517 nm. The x-ray analysis of the samples showed that the mechanical activation will help to increase the content of the active surface amorphous phase up to 40%. Adding of highly dispersed additive based on mechanic activated saponit-containing material to the composition of Portland cement after the interaction of this composition mixtures with water leads to the formation of submicrocrystals of the hydrosilicates from group of tobermorite. This fact was found by scanning electron microscopy methods. Record of absorption spectra in the infrared range of the samples was revealed of the fluctuations in the hydrosilicate groups, resulting in the following wave numbers 1440-1660 cm-1 and a broad band at 3300-3500 cm-1. This fact in agreement with the microstructural research. Thus, it is shown that the mechanoactivated saponite-containing material will be able to form the hydrosilicates of additional generation. The main conclusion of our work, based on our obtained results, allow us to use the saponite-containing waste as a potentially active mineral component in the binders compositions of hydration curing type.
