A Study of Feasibility in Shockproof Production from Bagasse
A Study of Feasibility in Shockproof Production from Bagasse

Bagasse is a load of waste of caster sugar industry about 20 millions tons per year over 80 percents are used to be fuel and raw materials for the other industries. Anyhow much more bagasse is abundant. Then attention in textile industry application. Because of biodegradable and environment friendly. This research was studied about fiber separation and shockproof production from the bagasse. Fiber separation by chemical process. There are variable in amount of sodium hydroxide boiling time and produced to web by field latex 100 percents at 100 degree celsius. Physical properties of web such as thickness weight per unit area bursting and tearing strength was estimated. The appropriate condition for fiber separation as follows : sodium hydroxide 180 g/l for 2 hours. Average thickness is 2.83-2.90 millimeter. Average weight per unit area is 0.57 g/in2. Average bursting and tearing strength are 371.1 N and 756 mN respectively. The web is suitable for shockproof production

การวิจัยด้านคอนกรีตพรุนที่เป็นมิตรกับสิ่งแวดล้อม

This research presents a study of the compressive strength flexural strength coefficient of permeability and superplasticizer requriment of Porous Concrete containing fine fly. Portland cement (CT) is partially replaced with pozzolans 0 20 30 and 40% by weight of the cementitious materials. The results show that the high compressive strength flexural strength and low total void ratio of Porous Concrete improves substantially with partial replacement of Portland cement with fly ash. Porous Concrete mix cement containing 20 and 30% of fly ash can be used to make cementitious materials. In addition the use of fly ash produces Porous Concrete mix with good compressive strength flexural strength total void ratio and coefficient of permeability.

This research presents a study of the compressive strength tensile strength flexural strength and water absorption of Cellular Lightweight Concrete containing fine fly ash and ground bagasse ash. Portland cement (CT) is partially replaced with pozzolans 20 30 and 40% by weight of the cementitious materials. The results show that the compressive strength tensile strength flexural strength and low water absorption of Cellular Lightweight Concrete improves substantially with partial replacement of Portland cement with fly ash and bagasse ash. Cellular Lightweight Concrete mix cement containing 20 and 30% of pozzolans can be used to make cementitious materials. In addition the use of fly ash and ground bagasse ash produces Cellular Lightweight Concrete mix with good compressive strength tensile strength flexural strength and water absorption.

Properties of footpaths slab agasse Ash Concrete
Properties of footpaths slab agasse Ash Concrete

This research was aimed to studying the effect of bagasse ash on the properties of footpaths concrete slabs. Using bagasse ash a waste from the manufacture of ethanol instead of the OPC type I 10 20 30 40 and 50 percent by weight. Test results revealed that the compressive strength of concrete bagasse ash mixtures was less than the plain OPC type I concrete And decreased by the content of the bagasse ash. The flexure strength of the footpaths concrete slabs was laid in the same direction. Comparison flexure strength of footpaths concrete slabs on the standard (TIS 378-2531) found that can used 40% replacement of bagasse ash replacing in cement. For the percentage of water absorption of footpaths concrete slabs in bagasse ash concrete mixtures were higher than the plain OPC type I concrete mixture and every mixture is not exceeding standard. It was also found that the replacing cement with bagasse ash content increased the cost of footpaths concrete slabs were lower down. When replacing cement with bagasse ash in 40% cheaper than the cost of plain cement were up to 31% and according to the standard
