1. Lightweight concrete: 2.1.1. Introduction: Foam balls lightweight concrete (FBLWC) has been a feature in the structural construction owing to its advantages over the normal weight concrete (NWC). It is a concrete weighing substantially less than that is made using gravel or crushed stone aggregates. Lightweight aggregate concrete is usually chosen for structural purposes which its use will lead to a lower overall cost of structure than will be expected with normal weight concrete. To gain perspective

The Development of Concrete and the Arch in Rome University of the People Introduction Ancient Rome is most recognized for its successful conquests, classical art, influential architecture, and diverse culture. While each of these achievements are certainly memorable, there are two other, lesser-known, accomplishments that ancient Rome deserves credit for. The first was that Rome popularized concrete and began using it extensively around 300 BC (Brewer, n.d.). The second accomplishment was that Rome

innumerable contribution to this modern world by many of its latest techniques. Many types of buildings with different technologies are being built all over the world, but construction using the concrete always occupies the top place. In all these constructions, usage of cement is unavoidable as it is the soul of the concrete. But we all know that the cement production has to be reduced due to the emission of carbon dioxide during its manufacture. Hence fly ash can be partially replaced with the cement and

2.1 INTRODUCTION The primary objective of every concrete mix designer is to achieve the desired hardened properties of concrete in the most economical way. This aim can be fulfilled if the various concrete ingredients are relatively proportioned to yield an optimized result. In order to comply with ACI recommendations, strength tests are usually performed between 7 and 28 days after the concrete has been placed. This is time consuming and also experimental errors are inevitable because the right

Post tension concrete is an advanced technique in the construction industry. It promotes higher loading concentrations, longer spans, thinner slabs, lighter structures and rapid constructions. The seventh sense apartment project in Colombo 7 is one of the first ongoing post tension constructions in Sri Lanka at the moment. I wish to observe this technique and intend to identify the setbacks in the system to check the suitability of such a technology in this environment. Currently they are constructing

Concrete is an artificial stone-like material used for various structural purposes. It is made by mixing a binding material (as cement) and various aggregates (inert materials), such as sand, stone chips, brick chips, brick chips, pebbles, gravel, shale, etc with water and allowing the mixture to harden by hydration. There are many types of concrete available, created by varying the proportions of the main ingredients below. In this way or by substitution for the cementations and aggregate phases

will begin by explaining what “concrete and the arch” are all about. Nowadays, a concrete simply means a strong hard building material composed of sand and gravel and cement and water, but in ancient Rome, a concrete is a mixture that included lime and volcanic sand. While arch on the other hand means a curved structure that is usually made of stone, brick, concrete, or, more recently, steel (Visual Arts Encyclopedia n.d.). Below is the development of both concrete and arch, their importance in the

Benefits Of Using A Residential Concrete Contractors When it comes to doing any type of maintenance or installation on your home, it can be tempting to try and do it yourself. However, as with a lot of projects, something like concrete work should be left to the professionals. The professional concrete contractors offer more benefits by having them do it instead of taking on a large DIY project. Save Yourself Time The one thing that is true in many households is the fact that everyone lives busy

The macroscopic material behavior of concrete is influenced by the geometry, spatial distribution and material properties of individual material constituents and their mutual interactions. Therefore, it is essential to study the influence of each material constituent in order to estimate the residual strength of the structural components. Thus, failure of concrete is a complex phenomenon due to its multiscale and multiphase nature. When the normal stress in a material reaches its tensile strength

This option is high in initial costs, but according to Brian Barber who is a reporter from the Tulsa World newspaper shared in an article in 2007 that concrete is less expensive than asphalt for long term results. It was reported that concrete lasts for about 60 years and is more durable than asphalt. It will resist erosion and handles your topography well.
