[002] Now a days, precast concrete products are becoming more popular as they have several benefit such as low cost, easily available, easy casting at site, ready to fix and having improved engineering properties. As this type of products manufactured in the factory, it will be having improved quality control and can be manufactured throughout the year. Another advantage of precast panel is that it can be resist more environmental effect as precast panel is cast in the factory not on the site. Hence drawback associated with casting of any concrete product can be overcome in this type of construction.
[003] On the other hand, the application of concrete without compaction/vibration has several advantages such as better and more reliable quality, better performance, dense and '0 uniform surface texture, improved engineering properties, faster and economical casting that is called as self compacting concrete.
[004] Self compaction concrete has ability to flow into mould under its self weight. This type of concrete does not have problem of bleeding and segregation. This type of concrete required less time of casting as there is no need of external vibration hence it is cost effective. Shortcoming of the conventional concrete such as poor flow ability and subsequent segregation/bleeding problem, delayed construction time have overcome in the self compacting concrete.
[005] Precast floor tiles is a type of product of concrete that is prepared, cast and cured at factory in the quality controlled environment with the reusing moulds. After casting, these floor tiles transported to the construction site. These precast floor tiles can be fixed at site with the help of normal labour. As this is the factory made product hence it is more economical and more practical.
[006] In this invention, our focus was on to produce concrete having more flexural strength as well sufficient impact resistance as compared to conventional concrete. Improved impact resistance is responsible for less cracking at same impact load. To achieve this goal, sugarcane bagasse was incorporated in the concrete to make self compacting in nature. By utilizing sugarcane bagasse, two benefits were achieved simultaneously i.e. environmental problem associated with sugarcane bagasse and reduction in consumption of cement in concrete.
[007] Regarding the sustainability, these precast floor tile having waste material i.e. sugarcane bagasse ash as well having less consumption of cement in the product. Simultaneously this newly developed product is having improved engineering properties such as flexural strength, impact resistant which are essential properties of any flooring material. Simultaneously, no compaction/vibration is required to develop this product as it is having self compaction properties.
[008] Precast floor tiles can be used in the parking space, ramp of any building, flooring of '0 porch of any building. These precast floor tiles can be fixed easily on site without any special fixing procedure and without any risk.
[009] Consequently, none of method is available in prior art utilizing sugarcane bagasse ash in self compacting precast floor tiles. And, there is a vital need of utilize waste product of sugar manufacturing unit in to sustainable construction as it is very difficult for sugar manufacturing units to reuse anywhere. In the areas of these manufacturing units, several environmental problems associated with sugarcane bagasse ash create. Hence, present invention provides a mix proportion of preparation of self compacting precast floor tiles containing sugarcane bagasse ash as partial replacement of cement.

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 of self compacting precast floor tile utilizing sugarcane bagasse ash. The proposed invention provides a mix proportion of '0 utilizing 10% sugarcane bagasse as partial replacement of cement in the preparation of precast floor tiles.
[0024] The proposed method provides utilization of sugarcane bagasse ash in the preparation of a self compacting precast floor tiles. These precast floor tiles formulation are produced using sugarcane bagasse ash of 10% of total weight of cement apart from its normal ingredient materials such as fine aggregate, coarse aggregates and water.
[0025] In the proposed method cement, fine aggregates, coarse aggregates, water and sugarcane bagasse ash utilized to produce concrete mixes for precast floor tiles. Proportions of various ingredients are shown in Table 1.
[0026] Table 1: Proportion of material to produce one cum of concrete for precast floor tile
Type of Cement Fine 10mm Sugarcane Water Superplasticizer concrete (Kg) aggregate Coarse bagasse (Kg) (Kg) (Kg) aggregate ash (Kg) (Kg) Conventional 425 975 605 0 192 3.9 concrete Concrete containing 382.5 975 605 42.5 192 3.9 sugarcane bagasse ash
[0027] In the preferred embodiment, the composition for preparation of concrete mix for precast floor tile comprises of cement (18.94%, 425 kg), fine aggregate (43.46%, 975 kg), 10 mm coarse aggregate (26.97%, 605 kg), sugarcane bagasse ash (1.89%, 42.5 kg), water (8.56%, 192 kg) and superplastizer (0.17%, 3.9 kg) for production of one cubic meter concrete.
[0028] Yet in the proposed method the sugarcane bagasse ash was used as cement replacement to produce self compacting concrete. The sugarcane bagasse was collected from manufacturing industry of sugar.
[0029] Mixing of sugarcane bagasse ash is carried out simultaneously with the mixing of cement and other ingredients.
[0030] In the further process, the precast floor tiles is cast into pre-defined mould of having size of 300mm x 300mm x 40mm. concrete was poured in the mould after mixing of all ingredients in the pan type mixer. As concrete is having self compaction in nature hence there was no need of vibration/compaction. After casting into mould, mould was left for 24 hours for setting and after that product was placed into curing tank for 28 days. During the mixing of ingredients, admixture/superplastizer was included to maintain the workability as well self compaction nature of fresh concrete.
[0031] Therefore the prepared product is tested in laboratory first for compressive strength, flexural strength, water absorption, abrasion resistance and impact resistance. In the testing, it is observed that compressive strength of concrete containing sugarcane bagasse ash is increased by only 3.53% at 28 days, in comparison of the conventional concrete as shown in Figure 1. Increase in the strength is attributable to the transformation of CH into CSH due to pozzolanic reaction. Flexural strength of this modified concrete increased by 10.90% as shown in Figure 2. Water absorption of concrete containing sugarcane bagasse increased by 4.72% as shown in Figure 3. Abrasion resistance is also increased by 18.68% as shown in Figure 4 which is within the permissible limit as per Indian Standard IS 1237: 2012. At the same time, impact resistance was increased 12.50% at the first crack where impact resistance was increased 15.79% at the ultimate failure as shown in Figure 5 and 6.
[0032] Table 2: Test results of precast floor tiles with sugarcane bagasse ash Test Results of conventional Result of modified concrete concrete containing sugarcane bagasse ash Compressive strength 31.20 MPa 32.30 MPa (Figure 1) (Figure 1) Flexural strength 3.12 MPa (Figure 2) 3.46 MPa (Figure 2)
Water absorption 1.06% (Figure 3) 1.11% (Figure 3)
Abrasion resistance 1.82mm (Figure 4) 1.48mm (Figure 4)
Number of blows 16 (Figure 5) 18 (Figure 5) required in Impact resistance at first crack Number of blows 19 (Figure 6) 22 (Figure 6) required in Impact resistance at ultimate failure
[0033] Therefore in the preferred embodiment it is confirmed that the sugarcane bagasse ash of total volume of cement in precast floor tiles can be used with improved compressive strength, flexural strength, abrasion resistance and impact resistance properties.
[0034] Additional advantages and modification will readily occur to those skilled in art. Therefore, the invention in its broader aspect is not limited to specific details and representative embodiments shown and described herein. Accordingly various modifications may be made without departing from the spirit or scope of the general invention concept as defined by the appended claims and their equivalents.
