The frictional characteristics at the slab-base interface are known to contribute to the development of the cracking pattern in continuously reinforced concrete pavement (CRCP) and also to its long-term performance. ... University of Illinois Urbana-Champaign data protection policy.
When a job involves a good deal of breaking concrete overhead, a useful tip is to fashion a kind of shield for the hammer. Find an old piece of rubber, about a foot …
Crushed concrete is made exclusively from old or destroyed columns, beams, reinforced concrete slabs, wall panels, trusses, and other load-bearing concrete components of building structures. Waste from washing concrete pumps and truck mixers, as well as defective products from reinforced concrete plants, are also processed.
Concrete floors and ground slabs in building frames contribute significantly to the overall embodied CO 2 footprint of concrete. One promising way to reduce the environmental impact is to tailor the concrete properties within a slab to meet spatially varied performance requirements such that concrete with a higher cement content is used only where …

Monotonic load tests have been conducted on plain and fiber-reinforced concrete slabs on ground to monitor the effect of fiber type and dosage on the strength properties of concrete slabs. The results revealed that simple material tests do not always successfully predict the contribution of fibers in cases where structural geometry and boundary ...
The steel reinforcement cage within the concrete slab consisted of two layers of 12 mm HRB335 steel bars and stirrups, accompanied by 6.5 mm plain bars spaced at intervals of 150 mm, as depicted in Figure 1(c). The steel girder and slab of concrete were connected by means of shear connectors.
