The Use of Reinforced Concrete in Modernism

– The usage of concrete was explored by the Early Christian and Roman architects but fell out of use throughout the Middle Ages and Renaissance period. The material was only fully explored again in the later half of the 19th century but only for mundane purposes where the material was cheap, easy to work with, and versatile, but most importantly it’s fireproof characteristic. In 1870, the idea of reinforcing the concrete was born; steel rods were to be inserted to increase its strength. Taking this principle, Ernest Ransome (America) and Francois Hennebique (France) both developed frame systems….  

Concrete Poetry – A Unique Genre

– Concrete poetry presents its readers with a unique and often confounding situation. In addition to using language or parts of language in non-traditional ways, concrete poetry also uses elements that are more commonly associated with visual art. However, concrete poetry is not visual art. It is still concerned, primarily, with the use of language, generally to communicate some meaning to the reader in a way that is undeniably linguistic in nature. Concrete poetry is therefore an especially unique genre that draws upon and incorporates many different concepts from a variety of disciplines in order to fill in the gaps left when traditional grammar and syntax are eschewed….  

Properties Of High?lime Fly Ash Concrete

– PROPERTIES OF HIGH?LIME FLY ASH CONCRETE ABSTRACT Fly ash is a waste product from coal based thermal power stations. About seven million tons of fly ash is being produced annually from these thermal power stations in Turkey. Concerted efforts are needed to make the material used to a great extent. These paper give the results of an investigation on the performance of fly ash concrete made with ASTM C class fly ashes from two sources. PC42,5 cement used in the experiments conforms to TS19 (Turkish Standards)….  

Concrete for Water Retaining Structure

– Concrete for Water Retaining Structure Author: Aritra Pal; Entry No. 2013CEC8314 1.0 Introduction: The Aim of this study is to select a better choice of water tight concrete for the water proofing construction of water retaining structures like tanks, reservoirs, swimming pools etc. This paper includes the study of early age & later age properties of concretes with Chemical Admixtures & Supplementary cementecious materials, from the aspect of water tightness & durability. 2.0 Principle of Water Tightness: • Concrete should be dense & durable • Concrete must have the capacity to withstand hydrostatic pressure without water seepage….  

Water Carrying Concrete Core

– … As for discharging, it happens in a complete passive way without any external influence as 60% of energy is transferred by radiations and 40% by convection. Structure of concrete core Water pipes are directly casted in the concrete core of the slabs generally in the center of the concrete slab to benefit from the concrete thermal capacity characteristics or near to the ceiling as around two third of heat transfer occurs through the ceiling and the rest through the floor. Generally heat flows from the water pipes in the direction of the slab surface in case of heating and opposite in case of cooling….
