Description

A Method and Mix Proportion of Eco-friendly Paver Block Containing Waste Brick Powder
Technical field of invention:
[001] Present invention in general relates to a kind of building material and more specifically to a composition comprising waste brick powder for preparation of eco-friendly paver block.
Background of the invention:
[002] In developing countries bricks are still one of the most popular construction materials. For brick making availability of good soil is crucial. Recently numbers of additives is added or are replaced with clay to increase the performance of bricks including fly ash, bagasse ash, rice husk ash etc. The utilization of waste from different industrial sector is appreciable for the environment and for the economy of the state also.
[003] The recent increase in infrastructure sector is resulting in increased production of bricks. The brick industry of India is managed by unskilled labor resulting in high amount of waste generation; the waste generated is a cause of environmental concern. The waste from the brick production facilities is also a cause of concern as the brick sector of India is unmanaged and has poor worker skill which causes high waste generation. The waste generated from the brick production can be broadly classified as brick dust/powder or surkhi, deformed bricks, over burnt bricks, broken bricks and fly ash.
[004] Bricks waste powder (surkhi) is waste produced during grinding bricks, brick-bats or burnt clay bricks. Brick Surkhi generally originate from two sources i.e. bricks industry (non hazardous industrial waste) and second source is associated with construction and demolition (C&D) activity.
[005] The proper utilization of brick waste in paver block protects the surrounding and human beings from the adverse effect of the waste generated and also maintains the environmental balance. Waste brick surkhi utilization in paver block has assorted considerable properties over raw ingredients (fine aggregate, coarse aggregate and cement) of the paver block i.e. inexpensive, doesn't consist of chemicals in the waste, easy obtainable, reduce accumulation of waste and reduces the storage problems of waste
[006] All the above mentioned benefits motivate to develop new product i.e. paver block by utilizing waste brick surkhi. None of research is available on utilization of waste brick surkhi in paver block.
[007] Although previously many attempts are made for providing the composition and preparation method of paver blocks by utilizing any other waste materials and thus few of the existing methods and compositions are found as- CN202898933U discloses a paving brick manufactured by virtue of building waste, US20140314990A1 discloses pavers and block composite materials and methods of preparation thereof, W02012044057A2 discloses a water permeable ceramic block composition, to a water-permeable ceramic block using same, and to a method for preparing same, US451466A discloses composition paving-block, W02014159832A1 discloses novel paving stones and construction block composite materials and methods for preparation thereof, US5997631A discloses hardener composition for producing waste-containing shaped cement articles and process for producing shaped cement articles using the hardener composition, W02017093821A1 discloses multi-purpose module or container or block prepared from mixed waste plastic, plastic type resins and related polymer.
[008] Yet in the art none of the invention provides utilization of waste brick surkhi in the preparation of paver block. And, there is a vital need of eco-efficient sustainable material which can overcome the adverse issues related with extraction of excessive sand mining by reducing its consumption using waste brick surkhi in concrete paver block.
[009] Thus the proposal of mixing of waste brick surkhi in concrete as fine aggregate replacement will become good alternative choice to minimize the adverse impact of excessive sand mining on the environment and environment effective approach for disposal of waste brick surkhi. Hence the present invention provides a composition for the preparation of paver block by utilizing bricks waste (surkhi) as replacement of fine aggregates.
Objective of the invention
[0010] An objective of the present invention is to attempt to overcome the problems of the prior art and provide an improved composition for preparation of paver block.
[0011] In a preferred embodiment, the present invention provides a composition and preparation of paver block by utilizing bricks waste in powder form (surkhi).
[0012] It is therefore an object of the invention is to minimize the consumption of fine aggregate by replacing it with waste bricks.
[0013] It is therefore a further object of the invention to provide an eco-friendly paver blocks having an improved abrasion resistance for medium type traffic.
[0014] These and other objects and characteristics of the present invention will become apparent from the further disclosure to be made in the detailed description given below.
Summary of the invention:

[0022] In order that the manner in which the above-cited and other advantages and objects of the invention are obtained, a more particular description of the invention briefly described above will be referred, which are illustrated in the appended drawing. Understanding that these drawing depict only typical embodiment of the invention and therefore not to be considered limiting on its scope, the invention will be described with additional specificity and details through the use of the accompanying drawing.
Detailed description of the invention:
[0023] The present invention relates to a composition comprising waste brick powder for preparation of eco-friendly paver block. The proposed invention provides a preparation of eco friendly paver block utilizing bricks waste (surkhi) as partial replacement offine aggregate.
[0024] In the proposed invention, for the preparation of paver blocks an eco-friendly concrete mixes are produce by utilizing cement, fine aggregates, coarse aggregates, water and waste bricks. The concrete mix design of M40 grade is made as per the guidelines of Indian standards IS 10262:2009 and IS456:2000.
[0025] In the preferred embodiment, the composition for the preparation of eco-friendly paver blocks comprises of cement (16.13%, 405 kg), fine aggregate (18.40%, 462 kg), coarse aggregate (54.52%, 1369 kg), waste brick powder (surkhi) (4.62%, 116 kg), water (6.13%, 154 kg) and superplasticizer (0.20%, 4.9 kg) for production of one cubic meter concrete. Proportions of various ingredients are shown in Table 1.
[0026] Table 1: Proportion of material to produce one cubic meter of paver block
Type of paver Cement Fine Coarse Waste Water Super block (Kg) aggregate aggregate brick (Kg) plastici (Kg) (Kg) surkhi zer (Kg) Paver block 405 520 1369 58 154 1.21% with 10% waste bricks Paver block 405 462 1369 116 154 1.21% with 20% waste bricks Paver block 405 404 1369 174 154 1.21% with 30% waste bricks Paver block 405 346 1369 232 154 1.21% with 40% waste bricks Paver block 405 288 1369 290 154 1.21% with 50% waste bricks
[0027] Yet in the embodiment, a waste brick concrete mix is prepared using all the above ingredients. Further in the proposed process freshly prepared mix is poured in paver block molds and pre-compressed using hydraulic pre-compression machine. After pre-compression, the paver blocks mold are kept as it is for 24 hours at room temperature and then de-molded for 28 days of standard water curing. The paver blocks are tested after 28 days of standard curing. According to Indian Standard IS 15658:2006, paver blocks are tested for compressive strength, flexural strength, water absorption and abrasion resistance.
[0028] In another aspect of the embodiment, compressive strength of the proposed eco-friendly paver block is observed for all replacement level however as per IS 456:2000 and IS 15658:2006 the acceptance value of compressive strength is achieved at 20% waste brick of replacement of fine aggregate (Figure 2). Flexural strength of paver blocks is much higher than desired flexural strength (Figure 3). The value of water absorption is less than 6% as per IS 15658:2006 for all replacement levels (Figure 4). At the same replacement level abrasion resistance of eco-friendly paver block is within the permissible limit as per Indian Standard IS 1237: 2012 (Figure 5). The test results of eco-friendly paver block at 10%, 20%, 30%, 40% and 50%waste brick as fine aggregate are shown in Table 2.
[0029] Table 2: Test results of eco-friendly paver block with 10%, 20%, 30%, 40% and 50%waste brick Type of paver Compressive Flexural Water absorption Abrasion block strength strength (%) resistance (mm) (MPa) (MPa) 30 MPa - 55MPa 6% (IS 2 mm (IS Requirement as per Indian (IS 15658:2006) 15658:2006) 1237:2012) standards Paver block with 49.02 4.47 2.34 1.02 10% waste bricks Paver block with 47.14 3.91 2.67 1.14 20% waste bricks Paver block with 43.52 3.82 3.31 1.36 30% waste bricks Paver block with 40.58 3.66 3.90 1.52 40% waste bricks Paver block with 37.33 3.31 4.87 1.79 50% waste bricks
[0030] Thus in the embodiment it is confirmed that the 20% replacement of fine aggregate by waste brick powder in paver blocks for medium traffic roads can be used without much affecting the compressive strength and whereas 40% waste brick can be used in paver blocks for light traffic roads like as domestic drives and public gardens.
[0031] The many features and advantages of the invention are apparent from the detailed specification, and thus, it is intended by the appended claims to cover all such features and advantages of the invention which fall within the true spirit and scope of the invention. Further, since numerous modifications and variations will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation illustrated and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
