Paper bricks are key construction materials for building in general and low cost housing in particular. The objective of is study is to develop light weight brick from waste wi minimum cost. The waste was collected, hydrated and spun to obtain pulp slurry mixing wi and cast into shape. The tests were conducted on bricks after drying and curing. Therefore ese bricks will reduce e dead weight of e structure to e considerable amount. So it changes our design and building cost as in economical point of view. KEY WORDS: light weight brick, compression test, efflorescence test, water absorption test INTRODUCTION: According to research, more an million tons of s are produced every year. It is estimated at by, mills will be producing million tons of each year. rd Pulp and is e P largest industrial polluted of air, water and soil. Since a large demand placed on e building industry, especially in e last decade, due to e increasing population which causes a chronic shortage of building materials, e civil engineers have been challenged to convert industrial wastes to useful building and construction materials. This experimental study which investigates e potential use of waste s for producing a low-cost and light weight composite brick as building material. These alternative bricks were made wi crete. Physical and chemical properties of and vary significantly depending on many factors such as geographical location and industrial processes. The main aim of is project is to compare e compressive streng of e bricks. So for is purpose, different percentage of %, %, % and of %, %,% (i.e. increase in wi decrease in content) and en compressive streng of bricks as established. Then wi e help of graph, a comparison between compressive streng, water absorption of ordinary bricks and bricks was determined. Before manufacturing e bricks, different properties of materials ( and ) were verified. After at, bricks were made and sun dried and some bricks ere oven dried and en wi e help of a compression testing machine (CTM), eir compressive streng was calculated. The purpose of is study was to use waste to produce light weight masonry bricks. EXPERIMENTAL PROCEDURE: Raw materials: The raw materials used are as follows. Cement: Cement is one of e binding materials in is project. Cement acts as a good binder wi to produce bricks. It hardens quickly when mixed wi and water. Ordinary Portland (OPC) confirming to IS -99 is used. 7

Description of test Initial setting time Final setting time Requirements of IS :99 mins Specific gravity. Less an minutes Paper: Paper is e natural polymer which consists of wood cellulose. The cellulose chain bristles wi polar OH group on adjacent chains, bundling, and e chain togeer. The chains also pack regularly in places to form hard, stable crystalline region at gives e bundle chains even more stability and streng. Water: Water is e essential material to mix all e above mentioned components. The quantity of water used is according to e workability of e mix. The ph of water used should be from a range of. to..water is required for preparation of mix and curing work during casting of blocks. The quality and quantity of has much effect on e streng of in construction blocks. EXPERIMENTAL PROCEDURE: Quarry dust: Quarry dustt Tis a waste obtained duringt TquarryingT Tprocess. It has very recently gained good attention to be used as an effective filler material instead of fine aggregate. In e present study, e hardened and durable properties of concrete usingt Tquarry dustt Twere investigated. And also physical and chemical properties of Quarry dust are obtained by testing e samples as per Indian standards. Property Quarry dust Specific gravity.7 Fineness modulus Unit weight.%.7 gm/cc In is study, six proportions were made for wi silica and wiout silica and it was shown in table. The quarry dust was kept constant and e and ratio was changed. For each ratio ten samples were prepared. The standard block size is 9x9x9 mm. In is project e block size is xx9 mm. The waste s were soaked in hours. The hand mixing was done for mixing e samples. Then e mixed sample was casted in brick mould of layers. Each layer is compacted uniformly. Subsequently e formed brick samples were removed from e mould as early as min and dried for at least days at room temperature. No damage was observed on e bricks while demoulding. Then it is cured and tested in compression testing machine (CTM). The testing was taken for 7P days and days and comparison graph is drawn.

The percentage of water absorption was found out by e difference in eir initial and final weights. specimen Dry weight Wet weight water absorption A B C.9.7. Efflorescence test: The soluble salts, if presents in bricks will cause efflorescence on e surface of bricks. For finding out e presence of soluble salts in a brick, is test was carried out. In is test, e brick were immersed in water for hours and en ey were taken out and allowed to dry. There was no any grey or white deposit on e brick surface hence it is free from soluble salts. Thermal Resistance Test: This test is conducted to test e samples for e effect of flame or high temperature. The initial weight of samples was measured. Then o e samples were kept at P PC in a muffle furnace and en ey were taken out and examined for burns and ashes. Then ey were weighted again using an electronic weighing scale. Cost Analysis: Cost of one brick = Rs.9. bricks- brick = Rs.. bricks- conventional clay bricks = Rs.. bricks- fly ash brick = Rs.. bricks- solid brick = Rs.7. Conclusion: Based on e experimental investigation, e following results have been found: The weight of bricks were found to be % to % lesser an e conventional bricks, hence it making weightless. The durability of bricks was found to be far more an conventional bricks. Streng aspects of Sample A and Sample B has similar streng as blocks which is higher of conventional blocks.
