Porroc - Pumice Perlite based aggregates for construction

Porroc -A perfect blend of Pumice & Perlite based Lightweight Aggregates 

Porroc-porous rock aggregates 


Porroc is the latest development in Litagg range  by GBC INDIA , a lightweight filler with unique performance properties and a wide  range of applications. Utilizing high-quality raw materials and modified process technologies
Porroc can be optimized for very low water absorption. Porroc is a multifunctional inorganic lightweight beads/ aggregate with bulk densities starting from 500-700 kg/m3  for quality building materials and industrial products. The creamy white spheres are porous  mineral  rock based  and available in different grain sizes from 2-6 ,8 -10 mm ,10-12mm


LIGHTWEIGHT CONCRETE USING PORROC :
The word ‘Porroc’ is a general term used for a range of porous materials produced during volcanic eruptions. Porroc stone strong and less porous. Its water absorption is as high as @15% . The major reason behind using porroc as an aggregate is its much light weight and comparatively high strength.
Porroc made from  light, spongy, highly porous kind of lava with a vitreous texture. Porroc has high silica & alkali and low calcium & magnesia content. Its spongy cellular texture is a result of the gases escaping from hot lava. It is having low strength and it is a good thermal insulator, sound insulator and fire insulator

The primary use of light weight concrete is to reduce the dead load of a concrete structure which then allows the structural designer to reduce the size of columns, footing and other load bearing elements. So the marginally higher cost of the lightweight concrete is offset by the size reduction of structural elements,less reinforcing steel and reduced volume of concrete, thus resulting in lower overall project cost.
Porroc pumice beads 

Due to porosity can also be used for fire protection, where they can shield structural steel from fire. They are also used as an insulating block. Light weight concrete LWC has been used to construct extremely large cantilevers, as the member can be narrower due to the decreased dead load. Using concrete of a lower density results in a lower dead load and can result in savings due to smaller member sizes. Occasionally this can allow construction on ground with a low load-bearing capacity.
 The porosity of lightweight aggregate provides a source of water for internal curing of the concrete that provides continued enhancement of concrete strength and durability, but this does not prevent the need for external curing.
Structural light-weight concrete has been used for bridge decks, piers and beams, slabs and wall elements in concrete and steel buildings, parking structures, tilt-up walls, topping slabs and composite slabs on metal decking. lightweight aggregates  beads for grc, cluster stone , stamped concrete

SINTAGG-Sintered Fly Ash Light Weight Aggregates

Sintagg-FLY ASH LIGHT WEIGHT AGGREGATES   Size : 4/8mm , 8-16mm  Sintagg- FlyAsh based lightweight (Low Density )aggregate by sintering process, can be  as a substitute for normal crushed stone aggregate, in making of concrete for structural and other applications.  The focus is empowering environment by making productive use of mounting stocks of fly ash – a nuisance by-product of thermal power plants.   Fly ash based Light Weight Concrete floor    Aggregates are used as a filler material in the production of concrete products such as blocks and floor panels in order to provide volume and hardness. In addition to some potential benefits to the concrete itself,  the use of fly ash as a lightweight aggregate in place of natural aggregate offers a wealth of benefits both economically and environmentally. Flyash based prefabricated steel structure Low Density Aggregate (LDA) It could be from natural sources or of man...

Artificial Low Density (LDA) light weight Aggregates

LDA -Sintered Flyash lightweight aggregates  Lightweight Aggregates (akin low density aggregate) is a generic name of a group of aggregates for structural concrete, mortar, or plaster that weighs less than usual rock aggregates including natural sand, gravel, and crushed stones. At an earlier stage, lightweight aggregates were mainly from natural origin, mostly volcanic pumice, etc. It is production  begins with mining or quarrying the raw material and with the development of mining machinery and technology, they can be manufactured from the natural raw materials like expanded clay, shale, slate(expanded about twice the original volume of the raw material) as well as from the by-products such as fly ash, blast furnace slag, etc. However, the natural pumice, vermiculite, and perlite can also be used as substitutes. The expanded raw material(excluding pumice) has properties similar to natural aggregate, but is less dense and therefore yields a lighter concrete produ...
