“…Бетон -один з найскладніших компо-зиційних матеріалів, для якого притаманні унікальні властивості [1][2][3]. Розробка висо-коякісних бетонів можлива шляхом аналізу результатів досліджень в області синтезу міцності і підвищення довговічності буді-вельних композитів і на основі більш пов-ного використання енергії портландцеме-нту, створення оптимальної мікрострук-тури цементного каменю, зміцнення конта-ктних зон цементного каменю і заповню-вача за рахунок спрямованого застосування різного роду хімічних модифікаторів і ви-сокодисперсних силікатних матеріалів [4][5][6].…”

140most cases are limited to use in flooring. Taking into account the physical and mechanical properties of magnesia concrete, we proposed to use it in the reconstruction (strengthening) of wooden floors to strengthen wooden beams. Magnesia concrete has high strength, adhesion, prevents the reproduction of bacteria and fungi, not combustible.The proposed method of reinforcing wooden beams significantly increases the operational characteristics of the floor.

Concrete Repair, Rehabilitation and Retrofitting II

There is no doubt that, over the past two decades, we have made enormous advances in the understanding and practice of concrete durability. Spurred by the often experienced early deterioration of reinforced concrete structures, with high capital investment for repair and rehabilitation, conceptions of design for durability have gained an increasingly higher level of importance in recent years. Durability design is beginning to be considered of equal importance as design for safety and serviceability. Nevertheless, durability concerns remain and early deterioration still attracts much expenditure. This paper is aimed at identifying important developments made in the field of concrete durability during the past two decades. Based on current design practice and current knowledge, future research and development needs are discussed, focusing on the influences of constituent materials, deterioration prevention methods, service life modelling of reinforced concrete structures, and performance-based test methods.far from settled and the need for continuing research and development remains. This paper therefore presents some reflections on the future research needs in concrete durability. Much of this discussion relies on observations of the extent to which researchers have addressed some of the 1 INTRODUCTION

“…OPC is expensive in the current market and not friendly to nature. By producing one ton of cement is associated with similar amount of Carbon dioxide (CO2) will be discharged into the atmosphere, currently more than 2.5 billion ton of cement is produced all over the world [2,3]. Cement replacement material (CRM) is one of the solutions for this problem.…”

AbstractMicrowave incinerator as one of the modern incinerators is proposed to produce amorphous Microwave incinerated Rice Husk Ash (MIRHA) with high pozzolanic reactivity thus can significantly enhance concrete properties. Analyses on the MIRHA with various burning temperature, the temperatures used were 300°C, 400°C, 500°C, 600°C and 800°C. To determine the physical and chemical properties of MIRHA with various burning temperature were also conducted through X-ray diffraction (XRD), X-ray Fluorescence (XRF), scanning electron microscope (SEM) and mechanical properties test. The results showed that the MIRHA at 300oC could be used as a cementitious material with optimum OPC replacement at 20%. It was found that MIRHA foamed concrete at 300oC achieved more than 100% higher strength compared to foamed concrete without MIRHA.Keywordsfoamed concrete, microwave incinerated rice husk ash (MIRHA), burning temperature.
