This study investigated the effect crumb rubber recycled from wasted tires on properties of structural lightweight aggregate concrete (LWAC). Two types were tested: control LWAC and rubberized (RLWAC). The consisted cement, fine (river sand), coarse (porous aggregates). For RLWAC, was replaced by at rate 10, 20, 30, 40, 50% volume. water to cement ratio for both set 0.35. experiment series dens...

Utilizing coral aggregate concrete (CAC) for construction on remote islands can significantly reduce cost and period, CO 2 emission, consumption of non-renewable energy. The durability reinforced CAC structures is critically influenced by their resistance to chloride attack. In this study, a reactive transport modelling was developed investigate ingress in CAC, which COMSOL-PHREEQC interface ba...

This paper is focused on the problem of optimizing the aggregate throughput of the Distributed Coordination Function (DCF) employing the basic access mechanism at the data link layer of IEEE 802.11 protocols. In order to broaden the applicability of the proposed analysis, we consider general operating conditions accounting for both non-saturated and saturated traffic in the presence of transmis...
