This chapter summarizes the attempts to utilize wastepaper sludge ash (WSA) and allied products in construction, in particular in concrete. The construction industry has been regarded by many as very conservative in its approaches, especially in terms of uptake of advances in various technologies. ...
Nevertheless, WSA is not recommended for use in concrete subjected to sulphate exposure.XIE, A.LALDJI, S.MIKANOVIC, N.International Congress on the Chemistry of CementXIE A, TAGNIT-HAMOU A. Wastepaper sludge ash: A new type of supplementary cementitious material used in concrete [C] //...
Mechanical properties Pulverized fuel ash Self-compacting concrete Wastepaper sludge ash Workability 1. Introduction Self-compacting concrete (SCC) is a modern and important type of high-performance concrete. It can compact and flow under self-weight without any external vibrations; it can also fill ...
This study evaluates fresh and hardened properties of fly ash geopolymer mortars incorporating calcined wastepaper sludge cured under ambient conditions. The calcined sludge geopolymer mixtures were characterized by XRD, XRF, and SEMEDS techniques. It was observed that addition of up to 40 wt% ...
An improved artificial fireplace log wherein the primary ingredient consists of paper waste sludge material that is recovered from settling ponds or clarifiers as waste material which is created during the manufacture of virgin or recycled paper. This waste sludge material is mixed with a suitable ...
Three dimensionally printed concrete (3DPC) is an interesting topic that has attracted increasing attention during the last few years. This paper offers a
The combustion process of MSW produces two residues: bottom ash and fly ash, in the daily generation ratio of 6:1 to 10:1 [17]. The bottom ash is the combustion residue discharged from the end of the grate furnace, about 20% of the total MSW, classified as nonhazardous waste. In com...
Stabilisation of soft soil using binary blending of high calcium fly ash and palm oil fuel ash 2018, Applied Clay Science Show abstract Hydrophobic concrete using waste paper sludge ash 2015, Cement and Concrete Research Citation Excerpt : Previous PSA research has focussed on hydraulic properties, ...
A successful valorization method for waste baby diapers should be able to effectively address waste diapers’ three main characteristics, in terms of high volume, pathogens, and high water-absorption capacity. Concrete is the most widely used human-made material on earth (Statista, 2018; WBCSD, ...
Still another object is to provide an agglomerate or aggregate that can be used as a construction material and is lighter in weight than a standard aggregate such as that commonly employed in concrete. These and other more detailed and specific objects of the invention will be apparent in view...
