Özet

© 2021 The Author(s)Foam concretes (FCs) have stronger matrix structure than lightweight concretes. The porosity of foam and lightweight concretes reduces as the density of the material increases. In addition, the porosity of lightweight concrete is highly affected by the aggregates’ pore features, and that of FC is totally affected by the pore structure of the matrix. Addition of ground calcium carbonate (GCC) and glass fibre (GF) to FC was investigated in this study. The effects of ingredients, namely, GCC, GF, cement and water on flexural and compressive strengths and the thermal conductivity properties were also studied. Test results were optimised in a proposed hybrid model. The optimisation results were also validated with laboratory tests. GCC incorporation increases compressive strength and thermal conductivity because of the filling effect. Furthermore, GF inclusion in the concrete mixtures contributes to the flexural strength of concrete.
