Effect of Presoaked Expanded Perlite Aggregate on the Dimensional Stability and Mechanical Properties of Engineered Cementitious Composites Atf #231;in Kopyala KESKN S. B., Sulaiman K., Smaran M., YAMAN . #214;.
Expanded polystyrene and perlite were added in different percentages to investigate the effects on some mechanical properties and thermal conductivity of concrete.
Mechanical properties and microstructural analysis of Expanded Perlite Aggregate (EPA) concretes are presented. Using 10% EPA, the effects of using various types of fibre were investigated.
#0183;#32;Expanded perlite aggregate (EPA) is a heat and sound insulator, and lightweight material which ensures economical benefits in constructions. This paper investigates the properties of concrete containing EPA considering cement types (CEM II and CEM I ), dosages (300, 350 and 400) and replacement ratios (0, 15, 30, 45 and 60).
The main objective of this study is to provide more data on the effects of expanded perlite on the mechanical properties and thermal conductivity of lightweight concrete. In the experimental program, mixtures were prepared by partially replacing natural aggregate by expanded perlite and as a result, unit weights of lightweight concretes in fresh state varied between 700 and 2000 kg/m 3 .
The expanded perlite (P) is a favorable material in terms of water retention, a negative material in terms of water absorption, capillary, permeability and mechanical properties [4].
The study presented here investigates the effect of density in cementitious mortar on its mechanical properties under quasistatic loading. The reduction in density was achieved through the addition of expanded perlite as a lightweight aggregate into cement paste by volume replacement of cement in the ratio from 0 to 8. This yielded a range of densities between 1000 and 2000 kg/m3.
Effect of Additive of Expanded Polystyrene and Perlite on Some Mechanical Properties and Thermal Conductivity for Mass Concrete Hamid H. Hussein1, Omar S. Saeed2 1,2 Technical College, Mosul, Iraq Abstract In this research, the major problem of mass concrete (Differences in Temperature) was studied.

This paper studied the produce process of the lightweight wall material (LWW). The main components of LWW were expanded perlite (EP) and Portland cement (PC). An experimental investigation was carried out to study the effect of EP on the performance of LWW, such as the bulk density, the strength property and thermal conductivity. The experimental results indicated that the products can be
#0183;#32;Properties of lightweight concrete, however, are usually different compared to those of normal concretes. The main objective of this study is to provide more data on the effects of expanded perlite aggregate on the mechanical properties and thermal conductivity of lightweight concrete.
