This objective research to study the possibility of used pozzolan material in the ternary blend by fly ash metakaolin and silica powder by replacement cement partially on the strength and resistance to chloride migration. Consideration of concrete with compressive strength in the range of 240-350 kg per sq. cm by varying the ratio of water/binder (w/b) there are three values are 0.4 0.45 and 0.50 and variable amounts of replacement cement some. The ternary blend of the fly ash metakaolin and silica powder of percentage of 0 2.5 5 10 15 20 and 25 by weight of cement. and the control specimens (w/b) without contain fly ash kaolin and silica powder the slump test in the range of 3-5 cm and the use superplasticizer to control the slump test of concrete. By casting specimens of cylindrical diameter 10x20 cm cube 10x10x10 cm and the beam size 10x10x35 cm after curing 28 days and test compressive tensile and flexural strength of concrete all specimens each ingredient by Chloride Migration Test method and the results showed that concrete is a mixture with pozzolan such as silica powder metakaolin and fly ash with amount increase replacement. The increase will help improve the quality of the concrete physical properties. The increased of compressive and Tension strength as the percentage increase especially to replacement cement increased by fly ash metakaolin and silica powder reduces the penetration of chloride in concrete respectively As a result of the porosity of the concrete with lower amounts of tightness concrete has increased

This research aims to study the possibility of steel fibers plastic fiber (polypropylene) fly ash and metakaolin mixed into the concrete. The concrete used in the research of the w / c 0.42 By 0.5 percent in the volume of steel fiber and poly propylene fiber in the amount of 0.25 percent by weight of the concrete. Concrete example of this test consisted of plain concrete(OPC).Concrete mixing materials pozzolan fly ash mixed plastics synthetic fibers of the type poly propylene fiber(FA/PP)concrete mixing materials pozzolan fly ash mixed plastics synthetic fibers of the type steel fibers (FA/ST) concrete mixing materials pozzolan meta kaolin mixed plastics synthetic fibers of kind polypropylene fiber(MK/PP) and concrete mixing materials pozzolan meta kaolin mixed plastics synthetic fibers of the typesteel fibers (MK/ST) by casting a cylindrical sample size 10 x 20 cm. Sample size 10x10x10 cm. cube and sample size 10x10x35 cm. beam. After 28 days and cure water concrete examples to test the strength of the pull compressive strength and flexural strength. And to test the movement of chloride through the concrete with Chloride Migration Test. Then bring the strength of the pull compressive strength flexural strength and the chloride permeability of concrete. Bringing concrete materials pozzolan mixed with synthetic fibers to develop the quality of concrete with improved efficiency and also reduces the porosity of the concrete. And permeability of chloride formed in the concrete (Only in landscape with the sea). The test can tell. Concrete mixing materials pozzolan with synthetic fibers to make a significant impact on the properties of concrete is improved as well. Depending on the type of polyester and the amount of material to pozzolan blended.

The purpose of this research is to improve the physical and mechanicalqualities of natural rubber latex tiles. Water: surfactant: surfactant: 1: 2.75: 0.03: 0.30:0.03: 0.04 by weight and added with natural latex. In the ratio of Portland Cement Type 1: Natural Latex is 1: 0 1: 0.025 1: 0.05 1: 0.075 and 1: 0.10. Formed with compression presses at normal temperatures it was found that the optimum amount of natural latex For concrete reinforced concrete tiles the ratio is 1: 0.025. The tests in accordance with Thai Industrial Standard TIS 535-2556 are tested in 4 aspects. Dimensional stress test Water absorption test And waterproofness testing The value has passed the benchmark. And low thermal conductivity. Increasing the insulation of the roof as well. Can be used as a prototype product tile concrete roof natural latex. To produce commercially And there can be many local latex or rubber latex. To be more useful and valuable.

This research aims to test the properties of concrete block mixed with basalt fragment as aggregates in products. The mix ratios of Portland cement type1 : basalt fragment : water are 1 : 10 : 0.7 1 : 10.5 : 0.7 1 : 11 : 0.7 1 : 11.5 : 0.7 and 1 : 12 : 0.7 by weight. The concrete block samples were mixed and casted in 7 x 19 x 39 centimeter by the concrete block molding machine. The concrete block sample testing follows the TIS 58-2533 standard on non-load bearing concrete blocks. From the results the density compressive strength and thermal conductivity of concrete block mixed with basalt fragment are lower than the common concrete block. In addition the water absorption and volumetric change are higher than the common concrete block. The optimal ratio in this work is 1: 11: 0.7

This research presents the engineering properties of asphalt (AC 60/70) modified with different ratios of rib smoked sheet. Then select the best properties of the binder to mix asphaltic concrete. From laboratory testing results with adding 9% rib smoked sheet into mixtures for the best results. The properties of asphaltic concrete can be improved by adding 9% rib smoked sheet. For asphaltic concrete Marshall Stability increased with adding rib smoked sheet into asphalt. Moreover the stiffness modulus of asphaltic concrete can be improved 9.03 compared to AC 60/70.
