Influence of aggregate size on compressive strength of pervious concrete

Construction and Building Materials, 2019
The aggregate size is an important factor influencing the compressive strength of pervious concrete. This work is focused on the study of the relationship among aggregate size, compressive strength, pore structure, cementitious paste thickness, and then ...

Effect of the high temperatures on the microstructure and compressive strength of high strength fibre concretes

Construction and Building Materials, 2019
The high temperatures of fires affect the physical and chemical properties of the concrete and thus influence its mechanical properties. This paper presents the results of an experimental investigation on the compressive strength at high temperatures of ...

Predicting compressive strength and electrical resistivity of eco-friendly concrete containing natural zeolite via GEP algorithm

, 2019
Concrete strength is dependent upon not only the water to cement ratio but also different constituents of the concrete. The inclusion of natural zeolite (NZ) as an effective supplementary cementitious material (SCM) creates reproductions through ...

Compressive strength prediction of recycled concrete based on deep learning

Construction and Building Materials, 2018
Considering on the current difficulties of predicting the compressive strength of recycled aggregate concrete, this paper proposes a prediction model based on deep learning theory. First, the deep features of water-cement ratio, recycled coarse aggregate
