This research presents a study of the resistance to carbonation compressive strength and porosity of concrete containing ground bottom ash. Three different of bottom ash finenesses viz. coarse bottom ash (GBA-1) ground medium bottom ash (GBA-2) and ground fine bottom ash (GBA-3) were used for the study. Portland cement (CT) is partially replaced with ground bottom ash at 0-40% by weight of the bottom ash. The water to binder ratio was kept constant at 0.5. Compressive strength porosity and resistant to carbonation of concrete were investigated. Fine bottom ash has a high potential to be used as a good cementitious material. The results show that the compressive strength and low porosity of concrete improves substantially with partial replacement of Portland cement with fine bottom ash. Concrete mix cement containing 10-20% of fine bottom ash can be used to make cementitious materials. The use of finer bottom ash produces concrete mix with good strength and resistance to carbonation.

This research examined the green packaging development from banana fiber for instant food products.The purposes wrer to construct approve and develop the sketch design; to develop banana fiber package prototypes that protect food products inside in order to eliminate packaging environment problems; and to save energy in package processing in the next decade.It was found that as for packaging design for instant banana food products such as stand-up pouchpaper box paper cupand zip lock paper bag the satisfaction of every factor was at a good level (4.12) and every packaging pattem conformed to the identity design in structural and graphical packaging As a result of studying structural packaging factorsthey were at an excellent satisfaction level in every packaging pattern including aesthetic and elegant packages(4.63) identity packages(4.56) and souvenir packages(4.53). The satisfaction for graphical packaging factors was at an excellent satisfaction level such as identity brand letters(4.65) and easier to recognize as follow.

This research studies the potential for using waste ash from industrial and agricultural by-products as a plastering material. This paper presents a study of the water requirement compressive strength flexural strength normal consistency setting time and air content of plastering material containing classified fly ash (FA) and ground rice husk ash (RHA). Fine fly ash and fine rice husk ash have a high potential to be used as a good pozzolanic material. The use of finer pozzolan results in a stronger and denser mortar which is due to better Q!spersion and filling effect as well as an increase in the pozzolanic reaction. Fine fly ash and fine rice husk ash can be incorporated into mortar as replacement of the mortar mix cement for the plastering. Mortar mix cement containing 20% fine fly ash and fine rice husk ash can be used to make plastering materials.
