Summary
Green pervious concrete utilizing water-quenched blast-furnace slag (BFS) and co-fired fly ash (CFFA) successfully replaced cement. Optimal mix design achieved comparable strength and permeability to traditional concrete.
Area of Science:
- Materials Science
- Civil Engineering
- Sustainable Construction
Background:
- Growing environmental concerns and the drive for a circular economy necessitate reducing cement usage in building materials.
- Green materials and cement substitutes are crucial for sustainable development in the construction industry.
- Pervious concrete offers environmental benefits but traditionally relies on cement.
Purpose of the Study:
- To evaluate the feasibility of a non-cement binder system for pervious concrete.
- To determine the optimal mix design for cementless pervious concrete using BFS and CFFA.
- To assess the engineering properties, specifically compressive strength, permeability, and durability, of the developed concrete.
Main Methods:
- Developed cementless pervious concrete by replacing cement with water-quenched blast-furnace slag (BFS) and co-fired fly ash (CFFA).
- Investigated binder ratios of BFS:CFFA at 40:60, 50:50, and 60:40.
- Tested specimens at different filled percentage of voids by cement paste (FPVs) of 70%, 80%, and 90% after 28 days of curing.
Main Results:
- Complete cement replacement (100%) with BFS and CFFA, without alkaline activators, successfully induced hydration, setting, and hardening.
- Compressive strength of cementless pervious concrete reached approximately 90% of control cement specimens after 28 days.
- The optimal mix, with a BFS:CFFA ratio of 7:3 and FPV of 90%, exhibited superior engineering properties and permeability.
Conclusions:
- Cementless pervious concrete using BFS and CFFA is a viable sustainable alternative to traditional concrete.
- The developed binder system demonstrates promising hydration and hardening capabilities without cement.
- The optimal mix design provides a pathway for creating high-performance, eco-friendly pervious concrete.

523
Concrete pavement joints are essential for maintaining the structural integrity and longevity of pavement by controlling where and how the pavement cracks. These joints can be categorized based on their functions, such as contraction or control joints, construction joints, isolation joints, and expansion joints.
Contraction joints are typically formed by sawing a groove into the concrete shortly after it has hardened. This creates a weakened vertical plane, deliberately encouraging cracking at...

Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Concrete is a vital construction material extensively used worldwide, primarily valued for its strength, durability, and versatility, which it provides for various structural designs. Concrete generally comprises ingredients like Portland cement, coarse gravel, fine sand, and water. Concrete can be mixed by simple hand methods or industrially at computer-controlled plants. The mixture consists of aggregates and a paste made from water and Portland cement. This paste coats the aggregates and,...

01:25Workability of Concrete
438
The workability of concrete is a crucial property that affects its handling, placing, and finishing during construction. It describes the ease with which concrete can be mixed, placed, compacted, and finished. Workability is primarily concerned with the concrete's movement and its ability to resist internal friction and external resistance from molds and reinforcements during the application process.
Concrete's workability is determined by its resistance to internal forces that arise...

01:25Reinforcements in Concrete

Reinforced concrete is a composite material used extensively in construction, combining the compressive strength of concrete with the tensile strength of steel. This synergy is essential as concrete, while excellent at resisting compression, is weak under tension. Steel bars, or rebars, are embedded in the concrete to handle these tensile forces. The choice of steel is strategic; it shares a similar coefficient of thermal expansion with concrete, which ensures uniformity in response to...
