In building material can we replace the reinforcement bar by the other ...
Of course yes! The most suitable replacement material would be fibers. Some commonly used fibers in concrete are steel, glass, carbon, aramid etc.

'If you replace concrete with any other material, it would have a bigger carbon footprint. Many people have the idea that if you built in steel you'd make things better - but in fact you'd make things worse. The reason concrete has a big carbon footprint as a whole is that there are just such huge quantities used.'
Alternate Cementitious Materials. Alternative cementitious materials are finely divided materiasl that replace or supplement the use of portland cement. Their use reduces the cost and/or improves one or more technical properties of concrete. These materials include fly ash, ground granulated blast furnace slag, condensed silica fume, limestone ...
With its main cementing ingredient being OPC But production of OPC comes at a cost both financial and environment that is why if OPC can be replaced to some extend by another material that is...
In our project, those shells are used as partial coarse aggregate replacement in concrete which is an effort towards protecting natural coarse aggregate for future generation. Coarse aggregate is partially replaced with 0%, 5%, 10% & 15% by oyster shells. Grade of concrete adopted is M30.
Answer (1 of 12): Concrete without cement is possible by the use of fly ash. The Green alternative to use of cement is fly ash which has same properties as that of cement both physically and chemically. Fly ash is an byproduct of thermal power plant as it's waste product is of no use but can be u...

It is eco-friendly, light in weight, strong and durable, and minimal fire hazards compared to thatch and other materials. These sheets can be used for roofing, walling, door and window shutters, and other components in building construction. ... concrete portions are replaced by filler materials such as bricks, tiles, cellular concrete blocks ...
Labor & material cost to pave concrete driveway. Labor costs to pave a concrete driveway are $2 to $4 per square foot or 50% of the total cost.Other cost factors include: Concrete prices are $2 to $3 per square foot for materials for a standard 4" thick driveway.A 5" thickness supports heavier vehicles like RVs but increases material costs by 20%.
The answer is cement. Cement, along with other common construction materials such as bricks, wood, steel and glass, is used almost universally in construction. These popular building materials have become so ubiquitous in large part thanks to their versatility, low cost and practicality. Nonetheless, they have their limits.
The average cost to replace the subflooring in a 306-square-foot room is $594, including plywood subfloor replacement materials and five hours of labor.For a DIY job with low-cost materials, a homeowner might pay as little as $428 for the same room, or as much as $2,981 to hire professionals to install premium subflooring.To replace concrete slab subflooring in the basement of a 1,500-square ...
Dump the concrete into the forms. Hold the mesh 2 in. above the gravel with small globs of concrete while pouring the sidewalk. Pour a few feet of concrete, heaping it slightly higher than the forms. Don't shovel concrete; pull it back or push it forward with a steel rake. Step 15.
It can replace up to 20% of traditional aggregate materials used in the making of concrete. There are limits to its strength but it is still a great eco-friendly alternative. Composite Cement The Bautex wall system which comes from the use of composite materials and foam beads is a great alternative to concrete.
AshCrete is a concrete alternative that uses fly ash instead of traditional cement. By using fly ash, a by-product of burning coal, 97 percent of traditional components in concrete can be...
An alternative is Dalton's Pli-Stix, a rope-like crack and joint sealer you melt in place with a torch. For holes 1 to 2 in. wide, use Dalton's Tamp & Set Patch ($9 for 3 1/2 gal.) or Trowel & Spread Patch ($6 per gallon). You can also mix sand and blacktop sealer until stiff and apply it with a trowel.
Cement, along with other common construction materials such as bricks, wood, steel and glass, is used almost universally in construction. These popular building materials have become so ubiquitous in large part thanks to their versatility, low cost and practicality. Nonetheless, they have their limits.
Hempcrete is a relatively new and biodegradable alternative to concrete. Hemp fibers when mixed with lime and water, create a concrete-like material, but lighter and stronger. Lime releases about 80% less carbon as compared to traditional cement and therefore Hempcrete can be said to test carbon negative.
As part of their future research, the scientists plan to investigate how other waste materials could also be used to replace concrete filler, and how locally-sourced sea sand could be used to ...
Replacement of Cement in Concrete P. Vipul Naidu1 and Pawan Kumar Pandey2 1Civil-SOT, Pandit Deendayal Petroleum University, Raysan, Gandhinagar, INDIA. 2Engineer, DMRC, Sector-18, Rohini, New Delhi, INDIA. Abstract Cement is a binding material, a substance that sets and hardens independently, and can bind other materials together.
A recent report by PBS features the invention of environmental chemist David Stone: a cement-like material that isn't just carbon-neutral but actually carbon- negative. Called 'Ferrock,' the material primarily contains iron dust and silica, both of which can be sourced via recycling.
A mix design for durable replacement concrete should utilize materials similar to those of the original concrete mix and include air-entrainment, appropriate selection of aggregates, and adequate cement and water content. Good workmanship should address proper mix, placement, and curing procedures.
Cement replacements such as PFA or GGBS save 850 kg of CO2 for every tonne of Portland cement saved. Using magnesia-based cements in place of current calcium–silica-based cements has the potential for large savings. Recycled aggregate, from demolished concrete or industrial mineral waste, will save CO 2, provided haulage distances are kept short.
The compressive strength of natural aggregate concrete and recycled aggregate concrete made with 10% SF were higher than the other corresponding concrete mixtures. At 28 days the compressive strength of concrete mixtures R-50-SF-10, R- 100-SF-10 were higher by 18.42% and 17.48% than that of R- 50, R-100 and also slightly higher than ...
Brick is one of the alternatives to a concrete driveway that looks great and won't cost you much. It can be semi-permeable if laid over sand and comes in many styles. Loose gravel makes for one of the cheapest driveway alternatives, though it can be high-maintenance when compared to other asphalt driveway alternatives.
Concrete is, after water, the second most widely used material on the planet. The manufacturing of concrete generates about 4.5 percent of the world's human-induced carbon dioxide emissions. Replacing even a small portion of concrete with irradiated plastic could thus help reduce the cement industry's global carbon footprint.
Ground Granulated Blast-furnace Slag (GGBS) as a cement substitute GGBS is a by-product of the iron and steel industry. In the blast furnace, slag floats to the top of the iron and removed. GGBS is produced through quenching the molten slag in water and then grinding it into a fine powder.
The optimum replacement level of rice husk is found to be to 10% for M30 grade of concrete. The effect of rice husk in concrete as cement and fine aggregate was studied in other paper [4]. Authors observed that the gradual decrease in the compressive strength as the percentage of replacement increases at 7 and 28 days.
It has been reported from the recent surveys that during the 2012 financial year, 247 MT of cement was used, which was increased to 550 MT in the financial year 2020. 1 Moreover, cement is ...
clay and shale materials are heat treated and ground to powder form to help control temperature effects in mass concrete, improve resistance to sulfate attack and mitigate alkali silica reaction. They are typically used as a cement replacement material in the range of 15% to 35% depending upon the project application. A particular pozzolan,
