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

The purposes of this research were to design and develop bags from Surins silk at Bam kae Yai community Ban Kae Yai Sub - district Surin The research instruments wewe 20 original bags questionnaire and training evaluation from The research findings were concluded as follows : 56 % female aged between 30-40 years. 41 % were government officers. 25.5 % get Bachelors Degree and averge income 10000-15000 bath. Bags type A B and C were appropriate in pattern style colour size total average 4.534.51 and 4.48 The participants were female aged between 30-40 years income below 5000 bath. before training the participants had little knowledge of designing and sewing bags from Surins silk after training they had more knowledge and needed more training
