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....   [tags: Ernst Ransome, architecture, concrete]

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....   [tags: Concrete Poetry Analysis]

Importance Of Compressive Strength Of Concrete

- 2.1 Introduction In a traditional way, a concrete mix is designed based on the code requirements and recommendations which uses the empirical values obtained from previous experiences. Compressive strength of concrete is determined by conducting standard uniaxial compression test on standard cylindrical sample specimens of ages 7 & 28 days, following the standard procedure and test values are reported in accordance with ASTM and ACI standards . If the strength value obtained from the test is less than the required strength after 28 days from date of placing of concrete, the entire process of concrete mix design has to be repeated until the required strength value is achieved, which is ti...   [tags: Regression analysis, Linear regression, Concrete]

Structural Lightweight Concrete

- Structural lightweight concrete is a type of concrete made with low-density aggregate, typically with a density of 1440-1840kg/m3, in comparison to normal weight concrete which has a density of approximately 2240-2400kg/m3. The 28-day compressive strength is needed to be greater than 17MPa. These values are achieved by using lightweight coarse aggregate and normal weight fine aggregate, generally including pyro-processed shales, clays, slates, expanded slags, and expanded fly ash. (NRMCA, 2003) The primary use and advantage of structural lightweight concrete is to decrease the weight in a concrete structure, and doing that allows there to be a reduction in the size of structural elements and...   [tags: proportional mix, aggregate materials]

Paved Surfaces Of The Construction Of Cities

- The introduction of paved surfaces to the infrastructure of cities was an impressive development in history. Concrete paved roads are formed by first placing a layer of fine subgrade, then filling granular concrete overtop that. Compared to the dirt roads of past, paved surfaces have greatly increased strength. This increase in strength not only allows paved surfaces to last longer as roadways than unpaved surfaces, but also provide a safer means of travel for cars. With unpaved roadways, there is a greater chance for pothole or uneven roadway, which could provide massive issues for vehicles and could lead to accidents or wrecks....   [tags: Road, Concrete, Water pollution, Hydrology]
