2. Clay Brick Waste Used in Mortar. Clay brick waste can be ground into tiny particles to be used in mortar. It can exist in two forms CBP and fine aggregates. The former exhibits pozzolanic activity to yield a denser mixture and the latter can be used as sand replacement.

Aggregate is a granular material such as sand gravel crushed stone used with a cement to produce either concrete or mortar. Aggregate is relatively inexpensive and does not enter into complex chemical reactions with water it has been customary therefore to treat it as inert filler in concrete and mortar.

In this study effects of crushed stone waste from Katununs quarry as fine aggregate on mortar and concrete properties will be examined. Samples with varying crushed stone waste replacement ratio ranging between 0 until 100 will be analysed at 3 7 and 28 days curing time. Mortar sample is using 0.5 wc ratio while concrete sample is using 0.45 wc ratio.

adhered mortar and thus calculating mix composition needs to be developed. This project deals with the review of the existing literature work for the use of recycled concrete as aggregates in concrete in respect of mainly the compressive strength and proposes an approach for use of recycled concrete aggregate without compromising the strength.

Jul 01 2020 In this study the feasibility of using ceramic waste as an alternative source for fine aggregate to improve the polishing resistance of cement mortar is investigated. The recycled fine aggregates used in this study originate from sanitary ceramic waste the physical and chemical properties of the Recycled Ceramic Aggregates RCA were determined.

Mar 01 2007 The major difference between RA and ordinary aggregates is the amount of cement mortar attached on the surface of aggregate. When old concrete is crushed a certain amount of mortar from the original cement mortar remains attaching to the stone particles in the RA which forms a weak porous and cracky layer Tam et al. 2005a Tam et al. 2005b.

This paper presents a study of incorporation of two types of construction and demolition waste CDW in rendering mortars as aggregates at 0 20 50 and 100 by volume. Recycled concrete aggregate RCA and mixed recycled aggregate MRA were used. The former is mainly composed of cementitious waste and the latter consists of a mixture of non-segregated wastes.
