Experimental study on the thermal performance of a hollow block ventilation wall

Renewable Energy, 2018
A hollow block ventilation wall (HBVW) is an innovative construction where the block cavity of the wall is used as a ventilation duct. Low-grade energy can be used to remove heat stored in the structure in summer and warm the structure in winter ...

Prestressed concrete hollow-block masonry

Building Science, 1973
Abstract This paper deals with prestressed hollow-block bearing walls. A linear analysis, consisting in finding the Airy Stress Function is presented. On the basis of the numerical solution of a sufficient number of particular cases, design information is offered in the forms of easily applicable graphs.

Low Carbon Geopolymer Hollow Block—Mix Design, Casting and Strength Comparison with OPC Hollow Block

2019
Cement masonry units are not considered as sustainable due to consumption of fuel, cement and natural resources and embracing alternatives is mandatory. Geopolymer is a green cementitious material and has excellent mechanical properties, consumes low energy in production and emits less carbon dioxide. The effects of paste volume, proportion of alkaline
