Selected Parameters of Mortars Containing Fine-Grain Modification of Glass and Clay Brick

Abstract:

Today’s world trend in construction and development of building materials is focused to research and development of material systems with properties resulting from dimensions of the components in the micro and nanoscale. Improved mechanical and physical properties, better durability as well as environmental and economic benefits are expected. Such of improved materials represent significant benefit for sustainable construction. In current world, construction and demolitions waste (C&DW) represents useful source of secondary raw materials for production of new building materials. This paper is engaged to assessment of impact the fine particles obtained by grinding of C&DW to technological and physico-mechanical parameters of mortar. Two types of different C&DW which vary in strength and microstructure were used for the experiment: glass and clay bricks. For the assessment of the properties of mortars with application of those ultrafine materials as filler, recipes with 20 and 60% replacement of natural fine aggregate were prepared and tested. Water demand for specified consistency was tested in the fresh state of mortars, while flexural, compressive and adhesive strength was tested after 2, 7, and 28 days of setting and hardening. Given results show positive or negligibly impaired impact of fine grain modification of glass and clay brick on tested parameters.
