การพัฒนาเถ้าแกลบและเถ้าถ่านหินเพื่อใช้แทนที่ปูนซีเมนต์ปอร์ตแลนด์ในงานคอนกรีตกำลังสูง
This research presents a study of the use of classified fly ash and ground rice husk ash as a pozzolanic material in producing high-strength concrete. Portland cement (CT) is partially replaced with classified fly ash and ground rice husk ash by weight of the cementitious materials. Compressive strength porosity and chloride penetration were investigated. The results show that the compressive strength resistance to chloride and low porosity of high-strength concrete improves substantially with partial replacement of Portland cement with fly ash and rice husk ash.

The purposes of this research were : 1) to study the formulation of eggshell clay suitable for development which is a new material in home decoration products inspired by stucco work Wat Phra Chetuphon Wimol Mangkhalaram2) to design and fabricate home decoration products from inspiring stucco work Wat Phra Chetuphon Wimol Mangkhalaram with eggshell clay and 3) to study the satisfaction of experts on home decoration products from the inspiration of the stucco work Wat Phra Chetuphon Wimol Mangkhalaram with eggshell clay. The processes of the research were to study the formulation of clay from eggshell by assigning 5 experts 3 clay mold experts and 2 clay sculptors and select the most suitable formula for 1 formula design and development of home decoration products inspired by stucco work Wat Phra Chetuphon Wimol Mangkhalaram 3 types: mirror frame lamp and vase 3 types of each type 3 types of design 5 experts 2 design instructors 3 interior designers 3 types of the most suitable type 2 interior designers selected the most suitable type for each type of 3 ones. Then fabricated products for home decoration eggshell molding from inspiration stucco work Wat Phra Chetuphon Wimol Mangkhalaram.There were 10 experts for product evaluation ; 5 of them were from clay expertises and the remaining persons were the product designs and inquire about the satisfaction of experts with the product. The results showed that: 1) experts give the highest level of satisfaction to an appropriate eggshell formulation equal to 4.25 in all areas in formula 1 2) research results for product designs experts are interested in choosing a home decoration product designs from the inspiration of the stucco work of Wat Phra Chetuphon Wimol Mangkhalaram with eggshell clay. Classifying products for mirror frame type 2 (3 people 60 %) lamp type 2 ( 4 people 80%) and vase type 1 (3 people 60%) and 3) experts have overall satisfaction towards home decoration products from the inspiration of the stucco work of Wat Phra Chetuphon Wimol Mangkhalaram with eggshell clay at the highest score In every aspect of satisfaction such as product functional material and satisfaction with an overall average score of 4.53 from 10 experts.

The study of the using Wolffia substitute for Pandanus in Kanom Piakpoon the purpose of this study is basic recipes of Kanom Piakpoon and to study the amount Wolffia substitute for Pandanus in Kanom Piakpoon. Used to the amount wolffia in different 4 levels : 0% 50% 75% and 100% of the Pandanus weight. The experiment is analyzed by Randomized Complete Block Design (RCBD) to evaluate the characteristic of appear color flavor taste texture (stickysoft) and overall. The characteristic evaluation is scored in 9 – Point Hedonic Scale. There are 80 participants including teachers and thired years students from foods and nutrition field who are not trained on food tasting the Faculty of Home Economics Technology Rajamangala University of Technology Pha Nakhon. The study is analyzed by analysis of variance (ANOVA) and Duncan’s New Multiple Range Test (DMRT). Statistical evaluation is also used to analyze. The study finding showed that accept amount of the using Wolffia for Pandanus in Kanom Piakpoon at 75% of the Pandanus weight. Highest every aspect. The characteristic of appear color flavor taste texture (stickysoft) and overall are in the moderate level were different with statistical significant (p≤0.05).
การวิจัยด้านวัสดุปูนฉาบที่เป็นมิตรต่อสิ่งแวดล้อม
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.

The objective of this research is to develop the precast adobe wall panel with high corrosion resistance and good thermal insulation. The ratio of Portland cement type1 clay rice husk ash straw rice husk waterproofed liquid and tap water was mixed and casted as same as the common concrete and reinforced by bamboo. From the results the proper prototype ratio of precast adobe wall panel was Portland cement type1: clay: rice husk ash: straw: rice husk: waterproofed liquid: tap water which equal to 1: 3: 0.3: 0.02: 0.02: 0.02: 0.4 by weight. The properties of the precast adobe wall panel prototype included density 1797 kg/m3 water absorption 16.70% bending strength 2.61 MPa compressive strength 21.40 MPa thermal conductivity coefficient 0.314 watt/m.Kelvin. Moreover the precast adobe wall panel prototype also was verified by TIS.2226-2548 with properties of impact resistance deflection and hardness in medium duty (MD) level. These straw and rice husk effected the precast adobe wall panel to decrease the density bending strength thermal conductivity coefficient and increase the compressive strength and water absorption.
