Recycled Concrete Aggregates (RCA) are not enough used in the construction sector due to their high porosity and water absorption capacity. Fine particles which composed of large amounts attached hardened cement paste even more difficult valorize, while they could be as mineral admixture mortar or concrete. The objective this work is find a recovery track for material addition. use porous powde...

Abstract This research investigated the reuse potential of pomegranate peels waste (PPW) in production fired clay bricks with improved thermo-physical and mechanical properties. PPW was used as a substitute for natural different replacement ratios ranging from 0 to 12.5% stride 2.5 wt%. The impact adding on compressive strength, total porosity, water absorption, bulk density, thermal conductivi...

The physical, chemical, and mechanical properties of mortars and bricks used in the historical building that was erected at Myra within the boundaries of Antalya Province during the Roman time were investigated. The sample picked points were marked on the air photographs and plans of the buildings and samples were photographed. Then petrographic evaluation was made by stereo microscope on the p...

We studied resonant laser interaction with Rb atoms confined to the interstitial cavities of a random porous glass. Due to diffusive light propagation, the effect of atomic absorption on the light scattered by the sample is almost entirely compensated by atomic fluorescence at low atomic densities. For higher densities, radiation trapping increases the probability of nonradiative decay via atom...

Sustainable waste management is becoming more and important in the construction industry due to increasing costs as well environmental effects. As a result of level wastes damage, use these has become focus for beneficial activities sustainable industrial applications. This study presents experimental results on effect performance cementitious mixtures. The scope this study, therefore, was asse...

salt crystallization is one of the most important weathering agents and may limit the durability of building stones. salt crystallization induces stresses inside the pores of stones. consequently, stone durability is closely related to its physical properties and strength. the purpose of this study was to propose a statistical model for estimating stone durability against salt crystallization c...

apart from other aspects, desert is a natural environment and is one of the appealing terrestrial elements. putting its symbolic and fictional senses aside, the term “desert” bears mystic sense more than material sense. in addition to the worlds materialistic experiences, desert has attracted the attention of writers because it creates a kind of inner experience, which returns the individual in...
