The durability of concrete different internal structures is different. We can use small water-binder ratio and add admixture to improve the tightness reduce defects. For achieve purpose improving durability, strictly control from raw materials, mixing, transportation, pouring, maintenance other process.

Over the past decade, the Texas Department of Transportation (TxDOT) focused research efforts on improving hot mix asphalt concrete (HMAC) mix design to preclude rutting in the early life of pavements. However, these rut-resistant stiff mixtures may be susceptible to long-term fatigue cracking due to oxidative aging. This project completed initial development of an HMAC mixture fatigue design a...

yoghurt is a unique fermented dairy product, consumed throughout the world and the trend ofconsumption is increasing due to its unique health benefits. yoghurt mix is often supplemented with msnf(milk solids-non-fat), it may contain as much as 5.7% unhydrolysed lactose. lactose can be hydrolysed withan enzyme lactase. deficiency of lactase in lactose-intolerant persons leads to gastrointestinal...

Abstract: Bottom ash is a hazardous by-product from coal based thermal power plants. In this study fine aggregate in concrete mix has been replaced with bottom ash and glass fibre is additionally used to enhance the strength characteristics of concrete. The concrete mix design is done for M30 grade concrete. The mix is prepared for different combinations of 0%, 30%, 40%, 50% and 100% of replace...
