This essay attempts a contrapuntal reading of Thomas More's Utopia. Contrapunctual reading, proposed by Edward Said. attempts to make a text speak across temporal, cultural, and ideological boundaries to a topic of present. I examine two opposite readings of Utopia around 2011 by both pro- and anti-Occupy Wall Street positions. On the one hand, the opponents of Occupy find its limits as a utopian social movement echoing in the fictional character of Hythrodaeus and the alternative society verbally sketched by him in Book Two of Utopia. On the other, Occupy's advocates read More's text as embodying its radial possibility. However, each shares the tendency to denounce Book Two, praising Book One in which Hythrodaeus vehemently criticizes England; they read Hythrodaeus not as an utopian idealist but as a social critic. The Occupy, as a result, is seen here as having an ambivalent relationship to utopianism. I reinterpret the radical possibilities of Book Two criticized by both pro- and anti-Occupy invocations of Utopia. Book Two provides a utopian space in which the existing social contradictions are cancelled, revealing the limits of the three partial utopias proposed at the end of Book One. Following Louis Marin's argument, I argue, the "utopic" space does not lie in the so-called ideal society described in the text but in the inconsistencies between the text's description(discourse) and topography(map). In Book Two the existence of a king is described, yet his space is not found in the topography of utopia; likewise market is described as existing at the center of a city, yet its space is not found either. These inconsistencies create a neutral space in which the ideological contradictions of the text are cancelled, and the space opens up the possibility of communal society beyond modern sovereign power and capitalism I argue this utopian dream needs to be summoned once again in our time as a compelling alternative to the corporate, capitalist order.

There are a large number of deteriorate mechanisms on the reinforced concrete structure and it acts complexly. In case of carbonation, it effected by environmental condition as well as properties of concrete. Most of all, water cement ratio and finishing materials have a great effect on the carbonation velocity. So, it is then aim of this study to suggest elementary data for the prediction of remaining life and the durability design by studying the relationship between carbonation velocity and permeability according to the waste cement ratio and kinds of finishing materials

The objective of this study is to obtain characteristics of early age pore-structure and carbonation of concrete using ground granulated blast furnace slag (GGBFS). The durability of GGBFS concrete should be evaluated for wide use of the GGBFS. As for that evaluation, an analysis on early age pore-structure characteristics of GGBFS concrete are very important, Carbonation depths of GGBFS concrete, which are known to be larger than that of OPC, are different according to replacement ratios and fineness of slag. Because sea sand as fine aggregate is much used recently, it is also necessary to analyze characteristics of carbonation of GGBFS concrete. In this study, The micro-pore structure formation characteristics of GGBFS concrete are obtained through the test of GGBFS mortars with different fineness and replacement ratio of GGBFS. The carbonation of GGBFS concrete is also investigated by acclerated carbonation test for early age GGBFS concrete.

This paper was studied to effects of fatigue by low flexural load on micro structures and carbonation of mortar. Mortar specimens cured at various conditions were first subjected to bending repeated loads, and it was made clear that insufficient cure reduced fatigue resistance of them. Next, fatigue tests that the stress levels are lower than the ones of fatigue rupture were carried out, The effect of curing conditions in early age on carbonation was furthermore studied using the scale, and it was made clear that insufficient cure is also susceptible to carbonation of them. Finally, the reason for rapid carbonation of fatigued mortars insufficiently outed was discussed from the view point of changes in pore structure of them.

Concrete used up to date semipermanent architecture material but now day concrete early deterioration emboss social issue because of construction structure and environmental factor. so, many study of deterioration concrete construction improve durability used impregnation alkalization agent. In These to Study of derelop reoairmeat material in reduce carbonation. xoncrete Building use Alkalinity Recovery Agent which is Realkalinity and strength surface. Alkalinity Recovery Agent undisposed application volume and cure the concrete period. To study Alkalinity Recovery Ahent spray and cure the concrete propriery in field.

The present age, it takes an interest in maintenance and preserve of the aged constructive materials cause destruction of environmental reason and a loss of resource. As answering question given to candidates at a civil examination, it is carbonated concrete construction materials to give alkalization agent to seek the plan to be extended durable life. The representative material, it was known for a chemical compound of alkailzation-Silica acid with Lithium and also used on inside and outside the country. But, it is so difficult to decide the effect because the work is to be repeated for a processing of construction. So, in this study, to investigate recovery faculty on a period of incubation that restrain processing of carbonation by impregnation alkalization agent, we were made good progress from basic test through comparative and analysis at laboratory and the spot of construction.

In reinforced concrete carbonation of concrete leads to depassivation of the reinforcement, and hence to initiation of corrosion. As a result of carbonation accelerating experiment with using effect of wet-dry cycle and 15% concentration of CO ₂, the carbonation rate shows very distinct difference according to W/C ratio. OPC-40 estimated no carbonation depth, whereas OPC-60 estimated rapidly the carbonation rate. The comparative analysis of the carbonation rate accelerating depends on different kinds of cement shows fastest FAC-20. Also, highly W/C ratio's concrete shows low half-cell potential value and fast corrosion rate. During period for 14 weeks. corrosion rate was not severe. So, it can be concluded that only carbonation attack on concrete doesn't severly deteriorated except very poor qualitified concrete.

Regardless of the carbonation of concrete is one of the importants causes of corrosion of reinforing steel in concrete with the cloride attack and the frost damage, the investigacion about the carbonation of concrete is limited and each investigator experiments under different condition. In this paper, the effect of temperature, relative humidity, concentration of $CO_2$, type of specimen, etc., were investigated according to the accelerated carbonation test. The principal conclusions from this research were as follows: 1) The carbonation of concrete is higher in olden of, under environmental condition(temperature-relative humidity, concentration of $CO_2$, ) of 40-40-10＞40-50-10＞40-60-5＞20-60-5. 2) Under same environmental condition, the carbonation of concrete in $\Phi$10$\times$20cm cylinder specimen is 2-8% higher then 10$\times$10$\times$40cm specimen.

Due to the tendency of increase in demolished-concrete produced by alteration and deterioration of concrete structures, recycling of those demolished-concrete is necessary to solve the exhaustion of natural aggregate, in order to save resources and protect environment. In this an experimental study herein, the Chlorine-ion and Carbonation resistance of the recycled aggregate concrete was investigated. Coarse aggregate was replaced with $100\%$ of the recycled aggregate and cement and fine recycled aggregate was replaced with various amount. It was shown that the concrete can obtain resistance of chlorine-ion, when fly ash replaced with up to $30\%$ of cement.

This study is performed to examine physical and mechanical properties or neutralization treatment point and curing methods of ECO-cencrete using rice straw ash. Tests for void ratio, compressive and bending strength with neutralization treatment point and curing methods are performed. The test result shows that the void ratio is decreased with increasing content of rice straw ash. But, the compressive and bending strength is increased with increasing content of rice straw ash. The greatest strength is appeared when neutralization is treated at the curing age of 6 days.
