Study on Floating Concrete by using Light Weight Materials

Stability of Floating Body Using Moderate Lightweight

The purposes of this research is to study the stability of floating body using moderate lightweight concrete of which the gross weight was modified by crumb rubber and polymer. The moderate lightweight concrete was prepared by replacing 10%, 20% or 30% of sand in weight with crumb rubber of size No.6 or No.26 and mixing with the fluid polymer latex in 7.5% or 15% of the weight of cement.

Green Concrete Seminar PPT with pdf report

Green Concrete Seminar and PPT with pdf report: Green Concrete is that type of concrete that is used to create the construction materials having a lesser effect on the environment. This version of concrete is made up from the mix of the industrial waste and inorganic polymer. The most commonly used way to produce green concrete is by using the industrial waste products such as fly ash, blast

Finishing Air-Entrained Concrete

Finishing Air-Entrained Concrete. Used in many applications, air-entrained concrete uses a chemical admixture (or sometimes, air-entraining cement) to produce a system of small voids during the mixing process. These voids are stabilized by the air-entraining admixture and remain in the hardened concrete

Experimental Study on the Properties of Hardened Concrete

used for the production of structural light weight aggregate concrete. A Mansoor Ali [6]studied the use of crumb rubber as a r e-placement material for fine aggregate. In this study, mechani-cal and durability properties of concrete with crumb rubber replacing fine aggregate and cement with silica fume were

High Strength Lightweight Aggregate Concrete using Blended

The use of just OPS as coarse lightweight aggregate in concrete mixture has some drawbacks for concrete. The aim of this study was to investigate engineering properties of a lightweight concrete containing both of these aggregates. For this purpose, in this study, 50% (by volume) of OPS was replaced with OPBC in an OPS lightweight concrete.

Uses: Tire-Derived Aggregate

Tire-derived aggregate (TDA)--made from shredded waste tires—is used for a wide range of public works projects and other civil engineering applications. These include slope stabilization, retaining wall backfill, lightweight embankment fill, vibration mitigation, and various landfill applications among others. The California Department of Resources Recycling and Recovery (CalRecycle

Lightweight concrete

Concrete is considered to be lightweight is the density is not more than 2200kg/m 3 (the density of normal weight concrete is assumed to be between 2300kg/m 3 and 2400kg/m 3) and a proportion of the aggregate should have a density of less than 2000kg/m 3. Lightweight concrete can be specified using the notation LC for the strength class, e.g

Estimation of technology progression and cost analysis for

used a mathematical model to study the performance and estimated the electricity cost and potential in such areas. The chimney in this system is not made up of concrete, but a flexible material is used for its manufacturing and it is also floating using lightweight gasses such as helium. The chimney essentially

Using Concrete to Reduce Wave Energy Costs

Whilst concrete is a widely used and well understood material in the built environment, its use in lightweight floating structures is less well established. To demonstrate the technical feasibility of using concrete for floating WECs, Arup developed two concrete designs to Front End Engineering Design level, working closely with contractor BAM

What is Lightweight Concrete? -Types, Uses and Advantages

Lightweight concrete mixture is made with a lightweight coarse aggregate and sometimes a portion or entire fine aggregates may be lightweight instead of normal aggregates. Structural lightweight concrete has an in-place density (unit weight) on the order of 90 to 115 lb / ft³ (1440 to 1840 kg/m³).
