Concrete Solutions for Sustainable Construction

In the construction sector, concrete is used everywhere due to its durability, versatility, and ease of creation. Therefore, it is crucial that it be utilised in the most environmentally friendly manner possible. This is why many engineers and contractors seek out a variety of environmentally friendly concrete solutions to apply their planning for more sustainable infrastructure.

Here are some ways that concrete is integrated into more eco-friendly practices:

Recycled Concrete Aggregate

Recycled aggregate concrete (RAC) often refers to concrete that’s left over from demolition and construction debris. This debris then wholly or partially takes the place of natural aggregates, which means that not as much mineral extraction is needed to develop new building materials. With a proper curing period of just over 90 days, RAC proves to be as structurally sound and effective as standard concrete, but engineers are still looking for ways to improve its durability in order to integrate it into more eco-friendly building projects.

Permeable Concrete Pavement

Permeable Concrete Pavement

Pervious concrete is essentially a structural concrete pavement that is porous, which allows for permeability. It is formed from a combination of cement, coarse particles, and water, just like traditional concrete. However, it has little to no sand, resulting in the porous, open-cell structure that allows water to easily travel through. The purpose behind integrating this material into more infrastructural projects is to reduce the amount of water runoff entering storm drains. Ideally, this water would go straight into the ground to keep aquifer levels stable. By stabilizing the groundwater level, (if not increasing it), this material would reduce the requirement for irrigation by diverting more water to tree roots and landscaping. Likewise, it would also decrease the number of contaminants that can pollute watersheds and damage delicate ecosystems.

Fly Ash Concrete

Fly ash is a fine-grey powder that is a byproduct of coal-fired power plants and is usually made up of spherical, glassy particles. Because it is a by-product and has a low energy content, fly ash is often described as an environmentally sustainable substance.

Its primary use as a cost-effective material is to increase the flexibility of plastic concrete and to enhance the durability and strength of hardened concrete structures. When this material is added to concrete, contractors can decrease the amount of Portland cement in the mix.

Geopolymer Concrete

This eco-friendly material provides another cost-effective alternative to Portland cement, just like fly ash. In fact, it’s mixed with fly ash and ground granulated blast furnace slag, which are waste materials from steel mills. In fact, this mixture improves the compressive strength of the concrete compared to Portland cement. After just 24 hours of installation, the compressive strength was found to be 25 MPa. Other beneficial traits include less drying shrinkage than standard concrete and enhanced resistance to fire and acid.

Low-Carbon Cement

Industrial cement is blended with mineral substances like calcined clays, fly ash, or blast-furnace slag to create low-carbon concrete. Depending on how much of these additives are used, concrete’s carbon footprint can be cut by as much as 70%.

Green Roofs and Living Walls

Green Roofs and Living Walls

Green roofs present an environmental advantage by decreasing stormwater runoff, assisting buildings in maintaining a consistent internal temperature, and lessening the impact of urban heat islands. The longer roof life and energy savings from heating and cooling are only two of the considerable financial advantages of green roofs.

Energy-Efficient Concrete Mix Designs

The concrete mixture, the type of mixer, the batch size, and the loading technique all affect how much energy is needed for the mixing operation. The definition of an efficient mixer is one that mixes all the components of ready-mixed concrete equally and with the least amount of energy. By monitoring mix homogeneity, we may shorten the mixing process and thereby cut down on power usage.

Rainwater Harvesting and Reuse

Rainwater Harvesting and Reuse

Urbanization’s negative environmental effects on receiving water bodies can also be mitigated by rain and stormwater collection. Thus, you might see more efficient systems developed to catch and store rainwater. The best material for this purpose would be concrete, which lasts longer than wooden barrels and won’t corrode like metal.

Carbon Capture and Storage

CCS (Carbon Capture and Storage) is a potent instrument for the mitigation of carbon gases in the environment since it allows industry to continue operating while producing fewer greenhouse gases (CHGs). In relation to concrete production, practices include:

  • Utilise recyclable and renewable materials in construction projects to cut down on harmful waste generation and energy usage.
  • Regulating waste management, including waste separation and recycling.
  • Transforming old structures through adaptive reuse.
  • Taking care of building sites to enhance conservation initiatives.
