The production of low-temperature clay lightweight aggregates is pursued eagerly as low energy and low cost lightweight aggregate concrete (LAC) building blocks become more popular. Clay ceramic hollow spheres (CCHS) with waste glass (WG) additive was developed and studied as aggregate in cement composite. CCHS with diameter 6–8 mm were produced by a sacrificial template technique with subsequent sintering at 900 °C. CCHS had differing WG content of 0 wt%, 5 wt%, 7 wt% or 10 wt%. The effect of sintering temperature and WG content on physical properties and morphology of the CCHS-cement composites were studied by means of optical microscopy and mechanical tests. Obtained composite materials were compared to commercially available lightweight fillers – foamed glass granules or lightweight expanded clay aggregates (LECA). The compressive strength of CCHS containing LAC is much higher (4.8–7.1 MPa) compared to LECA-cement LAC (3.5 MPa). Reduction of CCHS open porosity due to higher content of WG (10 %) leads to lower absorption of cement paste. This allows lower cement consumption, lower bulk density and higher compressive strength. LAC with CCHS proved to be promising construction material due to low-temperature production process (i), widely available raw material (clay) and secondary material (glass cullet) (ii), reduction of amount of cement paste needed for material production (iii).
