“…The lower density of fine RMA (4 mm-to-dust) was expected to be problematic. Poon and Chan [10] reported a 10% reduction in density of paving blocks when 75% crushed clay was used. The results from the mixes with coarse fraction replaced with RMA have been plotted as flexural strength versus replacement level, see Fig.…”

“…Such a precarious situation has prompted research related to alternative ways and means of balanced supply of equally good quality water from all possible sources including the treated effluents designated within the permissible quality criteria range 1 . However the unmatched potable quality of water is very difficult to obtain in as much as advanced technologies like the reverse osmosis or biosorption need to be employed.…”

Paver blocks, being the ideal utility blocks, are extensively in vogue for any pavement coverage due to the relatively easier and quick manufacturing process, mass production compatibility and lower unit cost. However the production involves huge usage of potable water that may inflict the availability of the same for building construction. A viable alternative without detrimental to the strength and the other related features of paver blocks would be exploring the usage of treated textile/dyeing industrial waste waters replacing potable water. A biosorption process aided by the coagulation-sedimentation method, using dry powdered water hyacinth leaves and petioles as coagulants is employed. This has the added advantage of harboring the fine bio sediments within the pores of the paver blocks resulting in lower porosities. Subjecting the biosorpted paver blocks to the standard quality tests as per IS coding (15658), empirical regression analyses on Compression strength and Flexural strength to withstand stationary and moving loads were applied. With reference to the curing spells of 3 days, 7 days and 28 days the improvised paver blocks had shown a relative increase attainable in the compressive strength as 4%, 3.6% and 2.4% respectively. The respective attainable increases in the flexural strengths were observed as 7.9%, 8% and 4.9% for the same curing spells. The results of this study exemplify the twin prospects viz., minimization of potable water requirement replaced by treated wastewaters and environmental protection by way of hiding the treated wastewater used for the mix within the paver blocks.

Demolition waste materials, such as crushed concrete and bricks, have been utilised by the UK construction industry for applications such as the production of concrete, low level backfill and road subbase. There has been increased research on the properties of the recycled aggregates in the past decade but it mainly concentrates on the strength of these types of materials through shear box and triaxial tests.Little research has been undertaken on the physical properties of recycled materials, such as particle shape, water absorption and freeze-thaw resistance. This paper addresses the investigation of the physical properties of demolition waste materials for the purpose of them being reused as engineering fill. It presents the physical characteristics of three types of commercially crushed concrete and brick materials, two of them being similarly based crushed concrete materials with different degrees of processing and one being crushed brick. Characteristics such as particle size distribution, particle shape, large scale compaction, resistance to freeze-thaw and aggregate impact and crushing values were established. The results show that there are similarities and differences between the two concrete based materials.

The characteristics of the brick based materials are significantly different from the crushed concrete materials.
