Abstract This paper presents the results, obtained after replacement of fine and coarse aggregates, in concrete mix, with tyre rubber. The tyre rubber, which has been used in the present study, is obtained after the mechanical trituration process of post – consumed tyres from trucks. Researchers have investigated, over the years, the use of recycled tyre rubber waste as a replacement for aggregate in concrete and its effectiveness. “Rubcrete-Mix” which would result from such replacement is found to have many engineering applications and holds promise in future. Rubcrete also possesses good mechanical properties and is considered to be one of the best and economical ways of recycling the used tyres. The present experimental study has the aim of arriving at the optimum quantity of the replacement material for the aggregates in concrete mixtures, for various engineering applications. For achieving a proper bond with the surrounding concrete paste, the recycled aggregates have been designed with respect to their size, shape and gradation. With the water – cement ratio being kept constant fine and coarse aggregate has been replaced with tyre rubber powder and chipped rubber and also cement has been replaced with silica fume. In preparing the concrete, Portland slag cement has been used along with super plasticizer less than 1% by weight of cement to achieve required workability of the resulting concrete. Furthermore, durability studies have been conducted and mixes have been designed for M30 grade concrete. Keywords: Concrete Mix, Mechanical Properties, Rubber Powder, Chipped Rubber, Silica fume.

Design of eco friendlypervious concrete
The document discusses the design and properties of pervious concrete. Pervious concrete is a special type of concrete with high porosity (around 30%) that allows water to pass through, reducing runoff. It is made without fine aggregates like sand. The study designed a pervious concrete mix without sand but with silica fume additive to increase strength according to ACI code. The mix is intended to be used for parking areas and roads to easily transmit water to the ground, maintaining groundwater levels. Pervious concrete has benefits like reduced runoff and flooding, increased groundwater recharge, and ability to filter pollutants from water.
Curing of concrete
Curing concrete is important to allow the cement hydration process to continue and develop strength over time. Proper curing ensures concrete reaches its designed strength and durability by controlling moisture loss. Common curing methods include water curing through ponding, sprinkling or wet coverings; membrane curing using plastic sheeting or curing compounds; and steam curing to accelerate strength gain. Curing should continue for at least 7 days for normal concrete and 14 days if blended cements are used. Inadequate curing can lead to reduced strength, increased permeability and poor durability.

Using plastic in roads provides benefits like increased strength and reduced costs, while helping address the problem of plastic waste. However, there are also potential disadvantages like toxic chemical leaching during construction and use. Overall, plastic roads present an environmentally-friendly way to strengthen pavements and reduce plastic pollution.
Plastic roads-the way ahead,Varun Suriyanarayana,August 2014
Challenges are a way of life. From challenges arise the endeavour to find solutions. Two such challenges that countries with large populations face are effective disposal of plastic waste and establishing a road network that is economical and durable. On the face of it, it appears odd to bring up two matters, so different in nature, together. However, there is a solution that connects the two problems. Current methods adopted to deal with plastic waste disposal worldwide include use of landfills and incineration. Both methods are known to have environmental and safety concerns. Today the majority of roads are constructed using either bitumen, tar or cement. Each of these have their own merits and demerits. Another kind of road has been suggested: plastic road. This provides a solution to the problem of effective disposal of plastic waste at the same time increases the strength and durability of the road, addresses the environmental, economic and most importantly safety issue.

Two such challenges that countries with large populations face are effective disposal of plastic waste and establishing a road network that is economical and durable. On the face of it, it appears odd to bring up two matters, so different in nature, together. However, there is a solution that connects the two problems. Current methods adopted to deal with plastic waste disposal worldwide include use of landfills and incineration. Both methods are known to have environmental and safety concerns. Today the majority of roads are constructed using either bitumen, tar or cement. Each of these have their own merits and demerits. Another kind of road has been suggested: plastic road. This provides a solution to the problem of effective disposal of plastic waste at the same time increases the strength and durability of the road, addresses the environmental, economic and most importantly safety issue.

Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.
