This research presents a study of the compressive strength porosity chloride penetration resistance to carbonation and corrosion of self-compacting concrete containing fly ash ground rice husk-bark ash and ground bottom ash. Portland cement (CT) is partially replaced with pozzolans 0-40% by weight of the cementitious materials. Fly ash ground rice husk-bark ash and ground bottom ash have a high potential to be used as a good cementitious material. The results show that the compressive strength and low porosity of self-compacting concrete improves substantially with partial replacement of Portland cement with fly ash. Self-compacting concrete mix cement containing 20-40% of pozzolans can be used to make cementitious materials. The use of fly ash ground rice husk-bark ash and ground bottom ash produces concrete mix with good strength and resistance to chloride and corrosion.

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 is a survey research. Its aim is an attempt to study and present the problems and Utilization of Instruction Innovations of Faculty of Industrial Education’s lecturesRajamangala University of Technology Phra Nakhon. The data collections were selected from population sampling of the Faculty of Industrial Education which consist of four departments with 38 lecture samples by using the purposive sampling. Research Methodology To study the problems and utilization of instruction innovations of the Faculty of Industrial Education’s lecture questionnaires were provided to collect data by using the average percentage value of standard deviation T-test and F-test technique. The following research results are : 1. The sexual differences of lectures has no any problems in using instruction innovation. 2. The different age levels of lecture have no problems in using instruction innovation. 3. For the lecture’s educational background there are no any problems in using instruction innovation. 4. Lectures in different departments of Faculty of Industrial Education have no any problems in using instruction innovation. 5. Lectures of Faculty of Industrial Education have a problem in using instruction innovation is at the moderate level. 6. According to the research results the most internal important problematic factor is the attitude’s lecture toward the necessary of instruction innovation. 7. The most external important problematic factor is the lack of financial supporting on production instruction innovation. 8. Lectures under the Civil Engineering and Mechanical Engineering department have problems in difficulty of using instruction innovation more than Electrical Engineering’s lecturers.

The purpose of the study were to survey A Tendency towards Undergraduate Innovation and Education Technology Application of the Instructors at Rajamangala University of Technology Phra Nakhon .Goal to development to innovation and educational technology for the future. Measurement and evaluation were to questionnaires in five academic in component form and use innovation and educational technology administration learning resource instructional and teching and system to learn . . The target population of the study were to 484 acadamic staffs Rajamangala University of Technology in 9 faculty .The represectative sample of 214 acadamic staffs were collected by means of questionnaires and analyzed by mean standard individual and descriptive statistics presenting in form of tables. The finding of the were that 1. Componen form and use innovation and educational technology transparency and overhead projector visualiz and video projector will be used for presentation 2. Administration oflice automation will be use for administrative purpose teleconference will be used for coinmunication and pulic relatio and intenet will be important learning resources. 4 learning resource will be web resource for instructional supprt and many kinds of digital learnind materials will also used. Internet online will be use by learners which will enable them to study at any times anywhereand used teleconference 5.Instructional and teching and system to learn The teacher will be encouraged to think analyze and development learning activity to student think analyze discovery to reference electronics in library.For the teaching to think that a Tendency towards Undergraduate Innovation and Education Technology intemet will be used by learner which will enable thern to study at any time anywhere. More learning centers will also be established in various institutions.
