Abstract
Lightweight cellular hollow concrete (LCHC) block is a type of masonry unit manufactured by precast technique. LCHC block is produced by the mixing of Portland cement, volcanic tuff powder, expanded clay aggregate and diatomite for building applications. LCHC blocks are lightweight and being frequent cellular hollow cleavages, give excellent thermal and acoustic performance, fire resistance and high weathering resistance to the buildings. In this research work, LCHC blocks with 28 different mixture batches were cast into a mould with vibro-compacting, de-moulded immediately and transferred to a storage area for curing up to 120 days in normal air condition. Totally 21 cellular space with 10 mm in width were placed in the block design. For each mixture, twenty four block samples were prepared and tested in the air dry condition for compressive strength and water absorption in accordance with BS 1881: Part 116. This paper initially examines how volcanic tuff powder affect the characteristics of lightweight concrete masonry mixtures and also investigates the use of quartet blends containing volcanic tuff powder, expanded clay aggregate, diatomite and cement to produce LCHC blocks for walls and partitions.
期刊介绍:
The scope of Teknik Dergi is naturally confined with the subjects falling in the area of civil engineering. However, the area of civil engineering has recently been significantly enlarged, even the definition of civil engineering has somewhat changed.
Half a century ago, engineering was simply defined as “the art of using and converting the natural resources for the benefit of the mankind”. Today, the same objective is expected to be realised (i) by complying with the desire and expectations of the people concerned and (ii) without wasting the resources and within the sustainability principles. This change has required an interaction between engineering and social and administrative sciences. Some subjects at the borderline between civil engineering and social and administrative sciences have consequently been included in the area of civil engineering.
Teknik Dergi defines its scope in line with this understanding. However, it requires the papers falling in the borderline to have a significant component of civil engineering.
