In this study, the performance of ultra-high performance concrete (UHPC) containing
expanded perlite powder (or expanded perlite sand) has been investigated …

Diatomaceous earth has a low density and this makes the material useful in producing
lightweight aggregates. Therefore, this research was conducted to study the mechanical …

Reducing the thermal conductivity of cement-based building materials can alleviate the
energy consumption and carbon dioxide (CO 2) emissions that are related to space heating …

Cementing is a significant operation that has important functions for supporting the oil/gas
wells life. Many additives had been added to enhance the cement layer properties towards …

This research describes the usage of crumb rubber (CR) and air-entraining agent (AEA) to
further reduce the density of lightweight cementitious composite into ultra-lightweight …

Interfacial shear stress transfer may occur in structural elements across concrete or between
concrete and steel. The fundamental contributing parameters which improve the shear …

In the current paper, an attempt has been done to produce insulating materials based on
alkali-activated slag (AAS) mortars, free from any foaming/blowing agent, with a good …

Various additives had been used to improve the properties of oil well cement. Perlite is a
material that occurs naturally and abundantly as a result of cooling the volcanic lava. The …

Different structural lightweight concrete mixtures of specific density and strength classes
were produced by using various lightweight aggregates (LWAs) such as pumice, perlite, and …

Concrete detachments in shotcrete-fortified tunnels are a hazard to workers and users that
can be reduced by changing density, residual load and bond strength. A factorial …
