The development of new lightweight concrete based on the valorization of local materials and waste in construction is an environmental and sustainable approach. In this context, the studied composite is a sand concrete (dune and alluvial) lightened by wood shavings to improve its thermophysical properties. The objective is to investigate the orient...

... simulation results shown in Fig. 3 to Fig. 6, and equations (3 and 4) was used to calculate the time lag (Φ) and the decrement factor (f) of the various walls (SC-WS). Summary, the results of the numerical simulation are reported in Table 3 with the various improvements. The best compromise between the time lag and the decrement factor for the double wall without coatings, for the two studied concrete are the south orientation and the east orientation, when considering the time lag that is ≥ 8 hours according to the climatic zone [9]. ...
