Rubberized concrete

In this study, a machine learning model, namely LightGBM, is developed to predict rubberized concrete's compressive strength (CS) using 11 input parameters. The model's performance is measured using several different statistical criteria after being trained on a dataset containing 275 samples.

Research objective of the project "Effects of crumb rubber content and curing time on the properties of asphalt concrete and stone mastic asphalt using dry process" evaluating the impact of relative fine CR (0-2.36 mm) modification and short-term ageing, determining the optimal percentage of CR and the effective absorption time in the range of 0- 5h for the optimal use of CR in asphalt mixtures demonstrating the possibility of introducing relative fine CR (0-2.36 mm) as a modifier into dense-graded AC using dry process.

Dairy farmers prefer different floor type like rubber, stones, gravels, bricks, concrete, mates and mattress etc. for providing comfort to the animals according to their own status. Poorly designed stall and bedding facilities cause an increased risk of productive, reproductive performance and lameness in dairy animals including decrease in there resting phase (Cook et al., 2009). Depth and height of bedding materials is also an important factor for dairy cows comfort.

Water based polymer systems are often used for improvement in the properties of plain cement mortar or concrete. Presently, latexes of a single or combinations of polymers like polyvinyl acetate, copolymers of vinyl acetate–ethylene, styrene–butadiene, styrene–acrylic, and acrylic and styrene butadiene rubber emulsions are generally used. One of the limitations of these polymer systems is that they may re-emulsify in humid alkaline conditions. To overcome this problem, an epoxy emulsion based polymer system has been developed.

Polymer modified mortars using either recycled waste concrete fine aggregate (WCFA) or artificial marble waste fine aggregate (AMWFA) were prepared and investigated for the purpose of feasibility of recycling. The replacement ratio of recycled materials also changed to investigate the effect of it on mechanical and physical properties. The water–cement ratio was increased as the replacement ratio of either AMWFA or WCFA in mortar in the absence of styrene-butadiene rubber (SBR) latex. The presence of SBR for both WCFA and AMWFA gave the increase of the air content.

The metal gates positioned on each side of the Level Crossing are approximately 4.3 m wide and open away from the railway. The surface of the intersection of the road with the track is covered in rubber „Strail‟ units, which gives a level surface over the track. Cattle grids are installed on each side of the roadway, where it crosses the track to prevent cattle straying onto the railway line. There is concrete post and wire fencing running between the gates and the boundary hedges, see Photograph 2. There is a residential house...

Death wore the seeming of a battered Chevrolet. The child's scream and the screech of rubber on concrete knifed through two seconds of time before snapping, like a celery stalk of sound, into aching silence. The silence of limbo, called into being for the space of a slow heartbeat. Then the thud of running feet, the rising hubbub of many voices. "Give her air!" "Keep back. Don't try to move her." "Somebody call an ambulance." "Yeah, and somebody call a cop, too." "I couldn't help it." It was the driver of the ramshackle Chevvie. "She fell off the curb right...

“God damn it, shit kicker, can’t you keep this thing straight?” “If I hear one more mother fucking word out of that aborted fetus you call a face I’m going to tear your balls off and bury them up your ass.” There was a painfully loud grinding sound as the car bounced and shimmied through the endless wasteland. Here and there the landscape was dotted with bits of debris, shredded rubber, cracked slabs of concrete, but by and large the years of harsh sandstorms had washed the area clean....
