Properties of Lightweight Composite Modified by Active Siliceous Admixture
Original language description
The paper is aimed at the application of diatomaceous earth and foaming agent in production of lightweight cement-based composites. The ordinary fine-grained composite mix was modified by diatomite powder admixture, in the amount of 20 vol. %. In the next step, porosity of the developed composite with incorporated diatomite was enhanced using foaming agent applied in the amount of 0.7 ml/kg of the blended binder. For the examined material, bulk density, matrix density, total open porosity, mechanical parameters and liquid water transport properties were tested in order to characterize the effect of diatomite and foaming agent on composite performance. Obtained results demonstrated high pozzolanic activity of diatomite that led to the decrease in porosity and thus improved mechanical resistance of composite. Although the foaming procedure resulted in a lower strength, increase in porosity is highly promising for production of lightweight materials having improved thermal parameters, low weight and other benefits.
