Key Parameter

Taking free shrinkage as the key parameter in evaluating cracking of concrete, the cracking properties of self-compacting concrete with strength grade of C35 and C50 were investigated based on ring and slab restraint tests. Meanwhile, the ultimate tensile strain of self-compacting concrete was studied by using flexural test. Experimental results show that the shrinkage of self-compacting concrete is lower than that of normal concrete. Self-compacting concrete cracks later than normal concrete with the same strength grade. Although the ultimate flexural tensile strains of self-compacting concrete in 7 d and 28 d are a little bit lower than that of the normal concrete, it can still be concluded from the research that the cracking property of self-compacting concrete can be greatly improved by using proper mix proportion.

Structure Crack

During the technology development of modem concrete, concrete structure crack (especially early-age crack) becomes more and more serious and has been one of main research directions of civil engineering. This paper aims at the seriousness of concrete structure crack and presents one of main cause is that concrete early-age (especially autogenous shrinkage) become large through the experimental study. autogenous shrinkage are mainly belongs to temperature cracks and desiccation cracks. Analyses the affection of ash and water reducing agent on the hydration heat, under the optimum proportion experiment which aims at reducing he hydration heat of cement. The best program are obtained that double mix with 20% fly ash and 1.5% water reducing agent .Design mortar’s early anti-crack experiment, and study crack-resistance and other mechanical properties based on different ages & different mix proportion. From the experiment, analyses early cracking under the influence of admixtures. The mix proportion of 20% fly ash, 10% slag and 1.2% water reducing agent can minimize the creation of cracks.

This experiment was designed by making a coal gangue with coal gangue, fly ash, lime power and a small amount of cement mixture selected from Dongpang coal mine in Hanxing area.We tested the compressive rebound modulus strength of the mixture, and according to the method of uniform design, 8 groups mix ratio were designed and the experiments on the coal gangue mixture in various mix proportion have been conducted. The experimental results were analyzed by regression analysis model, and the regression equation between the compression rebound modulus of coal gangue mixture and the blending amount of each admixture was established. Finally, using this regression analysis model, the influence of the fly ash, calces, cement to strength on the compression rebound modulus of coal gangue mixture was analyzed.

Abstract In this study concentrated on the development of GPC by using industrial waste products such as fly ash, alccofine (1203) and GGBS. GPC is an advanced eco-friendly concrete manufactured by activating source minerals rich in alumina and silica by alkaline liquids to form aluminosilicates based on inorganic polymers. Where cement was complete replaced with mix proportion of 50% fly ash, 25% alccofine (1203) and 25% GGBS for different molarities (8M, 10M and 12M) of alkaline activators which is solving the problem of unsustainable usage of limestone and pollutant related to the manufacturing process of cement. The present paper reports the cube compressive strength, cylindrical split tensile strength and flexural strength of GPC and which is compared with M25 grade of control specimens. It was observed that the strength of GPC is increased than normal concrete as molarities increases of 8 M, 10M and 12M. The paper explains about the effectiveness of fly ash, alccofine (1203) and GGBS materials.

Axially Loaded

Based on the experimental study foundation of setting altogether 10 bearing axially loaded long column of the autoclaved fly ash solid bricks. We had a comparative analysis on the fly-ash common brick with existing norms. At last, we get that ultimate bearing experimental value of autoclaved fly ash-lime brick masonry is higher than Theoretical ultimate bearing through research and analysis. It was said that it is reliable to calculate the load-bearing capacity of autoclaved fly ash-lime brick and column by design standard formula of masonry.
