Welcome to Mr.Hafeel to the stage. Give him big hand. He is an Engineer as well as he is an owner of ABD construction company. He is doing construction using alternative materials for steel & concrete. That’s why we invite him to speak to our degree holders. This is your time sir... Thank you Mr.Thanushan. Ok… let’s start our discussion with yours experience…

Timbercrete is an interesting building material made of sawdust and concrete mixed together. Since it is lighter than concrete, it reduces transportation emissions, and the sawdust both reuses a waste product and replaces some of the energy- intensive components of traditional concrete. Timbercrete can be formed into traditional shapes such as blocks, bricks, and pavers. Ashcrete is a low cost Nano Reinforced Impermeable Super Concrete made with Municipal Solid Waste Combustor Ash. Fly ash can be used as prime material in many cement-based products, such as poured concrete, concrete block, and brick. One of the most common uses of fly ash is in Portland cement concrete pavement or PCC pavement. Road construction projects using PCC can use a great deal of concrete, and substituting fly ash provides significant economic benefits Plain old wood still retains many advantages over more industrial building materials like concrete or steel. Not only do trees absorb CO2 as they grow, they require much less energy-intensive methods to process into construction products. Properly managed forests are also renewable and can ensure a biodiverse habitat. Ferrock is a new material being researched that uses recycled materials including steel dust from the steel industry to create a concrete-like building material that is even stronger than concrete. What’s more, this unique material actually absorbs and traps carbon dioxide as part of its drying and hardening process – making it not only less CO2 intensive than traditional concrete, but actually carbon neutral. HempCrete is just what it sounds like a concrete like material created from the woody inner fibers of the hemp plant. The hemp fibers are bound with lime to create concrete-like shapes that are strong and light. HempCrete blocks are super-lightweight, which can also dramatically reduce the energy used to transport the blocks, and hemp itself is a fast-growing, renewable resource.

Basalt Rebar reinforcement is an alternative to steel and fiberglass for

reinforcing concrete Made from volcanic rock basalt rebar is tough, stronger

than steel and has a higher tensile strength. Basalt rebar is naturally resistant

to alkali, rust and acids. Moisture penetration from concrete does not spall.

Basalt rebar has the same thermal coefficient expansion as concrete. Basalt

rebar is easily cut to length with regular tools. Basalt rebar does not conduct

electricity or induce fields when exposed to RF energy, great for MRI or data

buildings. Basalt rebar is perfect for Marine environments and Chemical

plants where corrosion is a continuous concern.

Bamboo might seem trendy, but it has actually been a locally-sourced building

material in some regions of the world for millennia. What makes bamboo such a

promising building material for modern buildings is its combination of tensile

strength, light weight, and fast-growing renewable nature. Used for framing

buildings and shelters, bamboo can replace expensive and heavy imported

materials and provide an alternative to concrete and rebar construction,

especially in difficult-to reach areas, post-disaster rebuilding, and low-income

areas with access to natural locally-sourced bamboo.

“Every building material comes with an environmental cost of some sort. However, some principles can help guide your choice of sustainable materials and construction systems. Careful analysis and selection of materials and the way they are combined can yield significant improvements in the comfort and cost effectiveness of your construction project, and greatly reduce its life cycle environmental impact”

I know you got a better idea about the alternative materials which we can used in construction industry. So you can use that knowledge when you working in the field. Good Luck all of you!!!
