In this paper present investigation is to assess the usefulness of industrial waste as a soil admixture, and focused to improve the compressive strength of the black cotton soil. Waste paper sludge ash (WPSA) is waste product from the Paper mill industries. The WPSA can produce a cementitious material because WPSA contains a large amount of CaO while it is pozzolanic material.
15-10-2018· This study used waste paper sludge ash (PSA) to treat three different clays. The aim was to assess PSA effectiveness as an alternative to lime or cement for clay stabilisation based on plasticity characteristics, unconfined compressive strength (UCS), water retention and volumetric stability.
One of the replacement materials is waste paper sludge ash (WPSA), a local industrial by-product generated abundantly by newsprint mills which possesses considerable cementitious properties. Parallel to this, the high amount of construction waste, particularly concrete waste has become a difficult environmental issue to cope with in todays world.

Waste paper sludge ash used in this study was collected from Malaysian Newsprint Industries Sdn Bhd (MNI), Pahang. The chemical analysis of OPC and WPSA is reported in Table 1. Natural fine aggregate, having a fineness modulus of 2.46 and specific gravity of 2.67 was also used.
09-09-2019· In this research, the results of experiments achieved on some mixtures of concrete comprising silica fume and paper waste ash as a substitute to Portland cement have been presented. The Portland cement was substituted with various ratios (namely 0,2.5, 5, 7.5 and 10 percent by weight of cement) of both silica fume and paper waste ash.
Influence of Waste Paper Sludge Ash (WPSA) and Fine Recycled Concrete Aggregate (FRCA) on the Compressive Strength Characteristic of ed Concrete. Advanced Materials Research Vol. 626 377 On another note, ed concrete is considered as a cost effective mix by maximizing the fine aggregate content in its production.
03-06-2011· Abstract: Waste Paper Sludge Ash (WPSA) is a waste material collected from the Paper Industry. WPSA is used as cement replacement in producing mortar and was investigated on its chemical, physical and mechanical properties. Construction material with natural resources now become limited and causes of air pollution and environmental problems.
Influence of Waste Paper Sludge Ash WPSA and Fine. One of the replacement materials is waste paper sludge ash WPSA a local industrial by-product generated abundantly by newsprint mills which possesses considerable cementitious properti Parallel to this the high amount of construction waste particularly concrete waste has become a difficult environmental issue to cope with in todays world...
includes such material as wastewater sludge, woodyard waste, causticizing wastes (from Kraft mills), mill trash, such as ship-ping materials, demolition debris, and ash from boilers (2). Currently, some of these residues provide 56% of the energy needs of the industry (1). The disposal of the remainder of this

Wastepaper sludge ash (WSA) is generated during the recycling of paper, which is an industrial by-product can induce pollution to the environment. Due to its effect related to pol
Abstract. One of all the problematic soil is the expansive soil. The expansive soil is soil whose high shrinkage, because of that need stabilization. The type of stabilization is
20-03-2019· Waste paper sludge ash (PSA) is a kind of by-product, which was produced by incineration of waste paper sludge from the paper industry. The amount of waste paper sludge is rapidly rising around the world annually, e.g. 11 million tonnes in Europe (Monte et al., 2009), 5.1 million tonnes in Japan (Kinoshita et al., 2017), 26 million tonnes in Korea (Jang et al., 2018); while in …
