  • PURPOSES: In this study the influence factors related to abrasion resistance of interlocking concrete block have been evaluated, and comparisons between various domestic and foreign abrasion test methods was also accomplished. METHODS: The modified rotational cutting method suggested in ASTM C 944 was applied. Surface materials with different types of fine aggregate such as crushed sand, sea sand, and mixture of crushed and sea sand were tested to compare the aggregate effect for abrasion resistance. RESULTS: The different surface mixtures with various W/C ratios, mortar and fly ash ratios have been investigated for functional and economical considerations. CONCLUSIONS: This study had obtained reliable results by changing diamond blade of rotating cutter. Therefore, in order to improve the abrasion resistance of interlocking concrete block for road, a new mix design was proposed.

  • In this paper, the properties of Interlocking block contained blast furnace slag cement are compared with that with O.P.C.(ordinary portland cement) and are analyzed under various mix proportions and the dosage of AE agent. According to the experimental results, compressive strength and flexural strength of interlocking block with blast furnace slag cement are lower than that with OPC. Also the strength and the ratio of absorption decrease with higher dosage of AE agent. although interlocking block with OPC has better performance than that of blast furnace slag in the side of quality, it is worth while to use the blast furnace slag as materials of interlocking block considered the side of recycling of resources and economy.

  • The incinerated municipal waste can be classified into two general types of ash; fly ash and bottom ash. The fly ash is appointed as specified waste, because it contains harmful heavy metals, ie Pb , Cd, etc. more than permitted standard index. The purpose of this study is to manufacture the non-sintering artificial aggregates using municipal waste incineration fly-ash and to evaluate their applications as coarse aggregates in concrete interlocking block. The test results of water absorpsion, strengths of the concrete block using artificial aggregates showed that the artificial aggregates could be used in part of 10-20% as coarse aggregate in concrete block.

  • Developed is a new environment-friendly concrete-block retaining wall system. The conventional analysis methods are not directly applicable because the proposed concrete-block wall system is made of by interlocking the blocks with shear keys. Therefore, the shear analysis as well as stability analysis have been conducted to secure the safety of block-wall system. Overall slope stability analysis was also performed. An appropriate strengthening method was developed to ensure the safety when the block-wall system is relatively high. The method of analysis for strengthening the concrete-block wall system was also proposed. The proposed environment-friendly concrete block retaining wall system shows reasonable safety and can be a good construction method for retaining walls and river bank walls.

  • The objective of this study is to investigate the properties of fine particles in the process of producing crushed fine aggregates under various fine particle contents. According to the test results, when fine particles are added as substitution of aggregates by about 10%, it shows that the qualities of interlocking block such as compressive strength, flexural strength and absorption ratio are improved. The application of fine particles provide various advantages in the sides of recycling of materials

  • The present age, it has been often reported that recycling of wasted glasses should he a great topic in related business circles. For the enviromental reasons, a public institution are looking for the ways of recycling these waste glasses. First of all, the purpose of this research is to recycle crushed and powdered waste glasses by substituting for the cement in mortar and concrete. the optimum replacement ratio of Powdered Waste Glasses(PWG) can be obtained from the pilot test results. Secondary, we made advances in recycling of waste glasses as recycled to make secondary concrete products. so, we manufactured concrete brick, block and interlocking block for side walk contained powdered waste glasses. finally, we compare properties among of concrete products to slove the economical and environmental problems.

  • Permeable polymer cement concrete in this study is one of the invironment conscious concretes that can be applied at roads, side walks, parking lots, interlocking block and river embankment, etc. In this study, permeable polymer cement concretes using polymer dispersion(St/Ac) with water-cement ratios of 25, 30, 35 and 40%, polymer-cement ratios of 0, 5, 10, 15 and 20%, and a ratio of cement to aggregate (by weight), 1 : 3.5(about 415kg/㎥), 1 : 4.0(about 375 kg/㎥), and 1 : 4.5(about 345kg/㎥) are prepared, and tested for compressive, flexural and tensile strength, and permeability. From the test results, increase in the strengths of permeable polymer cement concrete are clearly observed with increasing polymer-cement ratio, we can obtain the maximum strengths at water-cement ratio of 35%. The optimum permeable polymer cement concrete according to application and location of work can be selected in various mix proportions.

  • 본 연구에서는 콘크리트 2차제품 제조시 기체상의 이산화탄소를 주입하는 In-situ 탄산화 기술의 적용 가능성 분석을 위해 이산화탄소 주입량에 따른 콘크리트 인터로킹 블록의 기초물성 및 미세구조 분석을 실시하였다. 안정적인 이산화탄소 주입을 위해 CO2 가스 주입용 콘크리트 혼합 설비를 구축하였으며, 이산화탄소 주입량을 시멘트량 대비 0, 0.1, 0.3, 0.5, 0.7 wt.%로 제어하였다. 기초물성 시험 결과, 이산화탄소 주입량이 0.3 %까지 증가할수록 기존 배합 대비 높은 강도 거동을 보였으며, 주입량 0.5 % 이후에는 기존 배합보다 낮은 강도를 보였으나 콘크리트 2차제품의 강도 기준(보차도용 콘크리트 인터로킹 블록)을 만족하는 것으로 나타났다. 이는 콘크리트 인터로킹 블록 제조시 이산화탄소 주입에 따른 CaCO3 결정 및 C-S-H 등의 수화물 생성이 촉진된 것으로 판단되었다. 따라서 배합중 이산화탄소를 주입하는 탄산화기술을 다양한 콘크리트 2차제품 제조 공정에 적용할 수 있는 가능성을 확인하였다.
