“…Recently, the number of offshore and hydraulic projects in the coastal marine environment and the delta has increased several times. Based on some research analysis results, more than 50% of the nodes and structures of the coastal berthing and mooring facilities, breakwaters and tidal barriers, dry docks and jetties, container terminals, and offshore floating docks and drilling platforms in Vietnam were completely damaged or destroyed after 5 ÷ 20 years operation [2][3][4].…”

This paper reports the results of a research study aimed at identifying the compositional features of fly ash (FA) TPP “Pha Lai” (Vietnam), silica fume SF-90 (SF90) and superplasticizer SilkRoad SR 5000F (SR5000) contents that influence the sulfate resistance of corrosion-resistant concrete. The effect of FA, SF90 and SR5000 on the strength of corrosion-resistant concrete is obtained quickly, high early-strength concrete. In details, the compressive strength at the age of 1 and 3 days are respectively 29.6% and 61.13% in comparison to 28 days period. The deformation of corrosion-resistant concrete prisms in 5% sodium sulfate solution after 28 days of testing were determined by Russian standard GOST P 56687-2015. Using the mathematical planning method for four factors and the Matlab computer programs was obtained the mathematical model, which was adequately described the influence ofthe water-binding ratio, FA, SF90 and SR5000 contents on the concrete deformation. It was also noted that the effect of FA content is more pronounced than the water-binding ratio and content SF90. In addition, the effect of SR5000 content on the deformation of concrete is negligible, so it was discarded.

The benefits of using waste materials as a partial replacement for cement in high performance concrete are also discussed. This paper presents the combined effects of bottom ash TPP “Vung Ang” and expanded polystyrene aggregate on different the properties of light-weight concrete. Twenty different concrete mixtures with a water to cement ratio of 0.4 and superplasticizer to cement ratio of 0.015 were used. On the one hand, the EPS was partially replaced with (0 ÷ 40)% by volume of concrete mixture. On the other hand, the fine aggregate was replaced with (0 ÷ 30)% by mass of BA TPP “Vung Ang”. The engineering properties, including workability, density and compressive strength of light-weight concrete were investigated at different curing times. The level of decrease in the strength depends upon the replacement level of EPS and BA. Specifically, the concrete containing 40% EPS and 30% BA at 28 days of age decrease in average density and strength were 43.2% and 26.4%, respectively, in comparison with the control concrete.

The use of waste ash, lately a lot of research is done, in the manufacture of concrete, which aims as an added material, SCM cement replacement material, and so forth. Some ashes that have been used in research into the manufacture of concrete have been tested on chemical content, to determine whether ash from HVS paper waste can be used as a mixture for making concrete, in this experiment the parameters of the chemical content are tested according to the chemicals contained in chemical chemistry. Chemical content research using ASTM method, from the results obtained ash from paper waste ash has a high CaO chemical content above 90%, when compared with the chemical from rice husk ash where the highest chemical content of rice husk ash is SiO2, Conclusion obtained that paper waste ash can be tested as a mixture in making concrete because it has a high CaO content, when compared with the chemical content of cement where the chemical content in cement has a higher CaO chemical content.
