Twenty-four fifth grade (or equivalent age) students were assigned to one of two treatment conditions consisting of equal numbers of students from regular and special education classes. One group was involved in a dramatic games condition culminating in a theatrical performance planned by the group. The second group was involved in a noncompetitive games condition culminating in a demonstration...

The primary purpose of the review is to describe biological growth and its effects on goepolymeric ordinary concrete surfaces. As ages, surface alkalinity wears off by carbonation weathering,thus prepares a suitable environment for growth. Micro-organisms such as algae, fungi various types bacteria start accumulate subsequently penetrate into micro-cracks structures, resulting in bursting stres...

The use of industrial waste and/or by-products as alternative sources raw materials in building has become standard practice. result, more sustainable construction, is contributing to the institution a circular economy. Nonetheless, all necessary precautions must be taken ensure that inclusion and such entail no new health hazard for people or their environment. Due processes involved generatin...

Abstract Introduction: Recent studies have shown that the use of high-density nanoparticles (NPs) in concrete composition improves its radiation shielding properties. In present study, linear attenuation coefficients and photon scattering properties newly developed Nano-concretes been calculated using MCNPX Monte Carlo code. Material methods: The containing 10%, 20%, 30% weight percentage Osmiu...
