Mechanical, hygric, and durability properties of cement mortar with MSWI bottom ash as partial silica sand replacement

Popis výsledku v původním jazyce

A possible application of bottom ash (BA) produced in the municipal solid waste incineration (MSWI) facilities as a partial replacement of silica sand in cement mortar was studied. The particle size distribution of BA and silica sand was measured by laser-diffraction and standard-sieve methods. The composition of BA was analyzed using XRF and SEM combined with EDS. Additional basic characteristics of BA, such as pH, solubility in water, pozzolanic activity, powder density, and matrix density, were determined as well. For the cement mortars, basic physical characteristics and mechanical properties were firstly tested. Then, water absorption coefficient and moisture diffusivity were determined using the free water intake test and inverse analysis of moisture profiles, respectively. The moisture accumulation was characterized by sorption and desorption isotherms and water retention curves. Durability of cement mortars was assessed by the freeze/thaw resistance test. Experimental results s
