industry. Hypo sludge contains calcium and calcium chloride and minimum amount of silica. Hypo sludge behaves like cement because of high content of CaO and CaCl 2 and considerable presence of SiO and MgO. This silica and magnesium improve the strength and setting of concrete. Table 4- properties of hypo sludge S.no Property Result 1.

Dried sludge can be converted into artificial lightweight aggregates, slags or bricks for the construction industry.

sodium hypo- sodium cation chlorite hypochlorite anion The most common method for producing sodium hypochlorite is to react chlorine with sodium hydroxide (NaOH). The reaction by-products are sodium chloride (salt, NaCl) and water (H2O). 1) Cl2 + 2 NaOH NaOCl + NaCl + H2O + …

Hypo Sludge or paper mill sludge is a major economic and environmental problem for the paper and board industry. The material is a by-product of the deinking and re-pulping of paper.

The preliminary waste from paper industry is named as hypo sludge. In this study the material obtained from the paper industry waste (hypo sludge) is admixed with Portland cement at different replacement levels. The properties of concrete to be investigated include workability, setting time,

This hypo sludge contains low calcium and maximum calcium chloride and minimum amount of silica. Hypo sludge behaves like cement because of silica and magnesium properties. So Hypo sludge may be used as partially replacement of cement. So we can use Hypo sludge as a partial replacement of cement in pervious concrete.

properties of bricks enhance till 15% but after that strength of bricks reduce and water absorption increases. 3. Yadav, and Agnihotri (2014), experimentally described the recycling of waste product that is STP sludge (also known as hypo-sludge) and fly ash by adding in them to bricks. In their

The following tables 4 – 6 and Fig. 8 show the hypo sludge chemical properties and comparison between cement and hypo sludge.The hypo sludge waste from paper industry near the province of Batangas will be used in this experimental study.

composition of 7.5%, 10%, 12.5% and 15% of hypo sludge which is used in order to reduce the weight of concrete cement mechanical property also known as compressive strength. It is evaluated on cubes with dimension 150 x 150 x 150 mm and their analysis results are obtained on the basis of strength after storing it for 28 days. Sumit et al. (2013 ...

This paper summarizes the research work on the properties of hypo sludge when used as partial replacement for Ordinary Portland Cement (OPC) in concrete. OPC was replaced with hypo sludge by weight at 0%, 5%, 10%, 15%, 20% and 25%. 0% replacement served as the control.

conditions for transforming paper de-inking sludge into pozzolanic [4]. They dry hypo sludge was burnt in an electric laboratory furnace from 6000C to 8000C for 2 and 5 hours. The resulting products were grounded and sieved to a particle size of under 45 ä I. The mineralogical composition by X-

sludge is found to be 2.17. The chemical composition of cement and Hypo sludge is presented in Table.1. 3.0 EXPERIMENTAL PROGRAM . In this research work an attempt is made to produce sludge concrete specimens constituting hypo sludge. The proportion of binder components (i.e.) the percentage of hypo sludge is taken as 10%, 20% &3replaced with 0%

the examination of various properties of the brick. Results shows that proposed work has achieved good set of strength with increase in percentage of Fly-Ash and Hypo-Sludge. It was obtained that density of dry compacts decreases with increase in weight percentage of Fly-Ash and Hypo-Sludge.

also known as hypo sludge [9], paper mill sludge, and fibre clay [10]. A large quantity of sludge is ... hydraulic binder, as high CaO content means the material is likely to have cementitious properties. The mineralogical composition of incinerated waste paper ash is mainly Calcite 84.4%, Talc 11.0%,

The organic part of the sludge decays more rapidly, with an increase in the quantity of finely dispersed and colloidal particles and bound water resulting in a decrease in the separation of water from the sludge and poor dewaterability. The density of primary sludge is 1.0 to 1.03 g/cm3, and the density of activated sludge is about 1.0 g/cm3 ...

composition, Geopolymer concrete is an eco-friendly concrete [4]. The reutilizations of waste materials are really ... Hypo sludge is one of the waste materials produced from paper industry having almost similar properties as that of cement. Hypo sludge behaves like cement because of silica and magnesium properties [6]. To add the workability ...

II. HYPO SLUDGE Hypo sludge is also known as paper industry waste. It is the byproduct of the paper waste. This hypo sludge contains low calcium and minimum amount of silica. Hypo sludge behaves like cement because of silica and magnesium properties. Hypo sludge …

Pitroda et al. (2013) studied the properties of Hypo Sludge in concrete to check its durability. The water absorption of Hypo Sludge The water absorption of Hypo Sludge in concrete shows lower water absorption at 10% replacement for M25 and M40 grade concrete.
