Durability of expanded polystyrene mortars

Historic Mortars: Characterization and Durability. New Tendencies for Research

A mortar is a material resulting of the intimate mixture of sand grains, a binder (lime, cement, etc.) and water. The properties and characteristic of the mortars mainly depend on the nature of the binder component. That is the reason for which, its evolution with time has been very related to the development of artificial cementitious materials. So, with the consolidation of the Roman civiliza...

06 Field efficacy of expanded polystyrene fc.indd

Concerns about traditional chemical pesticides has led to increasing research into novel mosquito control methods. This study compared the effectiveness of 2 different types of polystyrene beads for control of mosquito larvae in south-east Islamic Republic of Iran. Simulated field trials were done in artificial pools and field trials were carried out in 2 villages in an indigenous malaria area ...

Recycling of Expanded Polystyrene Using Natural Solvents

Implication of expanded polystyrene and shredded waste polystyrene to control Anopheles spp, Bandar Abbas and Chabahar, Iran

Introduction: Due to insecticide resistance, environmental pollution and difficulty in biological control, usage of conventional larval control measures are not applicable in mosquito breeding places. As part of Integrated Vector Management program, we aimed to asses the effectiveness of two polystyrene beads types for Anopheles spp larvae control under laboratory, semi-field and field cond...

use of expanded polystyrene (eps) and shredded waste polystyrene (swap) beads for control of mosquitoes

background: mosquitoes transmit several diseases to human. there are several measures for control of larvae. as part of integrated vector management (ivm) program, the utility of floating layers of polystyrene beads (eps) is a po­ten­tial alternative in habitats of mosquito larva. eps beads prevent oviposition of mosquito as well as killing the im­ma­ture stages by forming a tick layer on the w...
