The reasons forconcrete mixer are partly the rising costs of primary raw materials (and their regional scarcity) and partly also a growing awareness of environmental problems. Widely varying pressures can be observed on the environmental side. Because of emissions trading there is much emphasis in the leading industrial nations on the reduction of CO2 emissions during the production of cements. In addition to this the emergent industrial nations, such as India and China, have not yet developed any adequate ways of utilizing industrial wastes, resulting in a search for possible ways of utilizing the large amounts of ash and slag produced. It is hoped that binders based on geopolymers (GP) will prevent the large-scale landfilling of ash and slag, with the corresponding conservation of primary raw materials, and also cause the emission of significantly smaller quantities of greenhouse gases when compared with cement-based binders.
1.Influence of timely clean on mobile concrete mixer
Clean the
cement mixer by dumping the excess concrete in a 30gallon trash can and rinsing out the mixer with a hose,until the water runs clear. Catch everything with thetrash can. The water still contains active cement;never pour it down the drain. Let it sit for 24 hours.The heavy stuff will settle to the bottom and then youcan pour off the water. Dump the sludge out onto atarp, let it dry Skid Steer Loader, and then disposeof it.

A cement mixer requires thorough cleaning after everyuse. If you fail to maintain your mixer properlymobile block machine, the drum can become coated withdried concrete and gravel, and the longer you wait toclean it, the more difficult the job. For this reason,always clean your mixer immediately after you completeyour work for the day. This will save you from havingto chisel out hardened concrete or break out corrosivechemicals
2.Cooler water will lengthen working time of concretemixer
The drum of the mixer has fixed paddles attached tothe inside. When the mixer is rotating, these paddlespick up the concrete, pull it to the top, and thengravity lets it fall down on itself. This churningmotion mixes the concrete. If the drum of the mixer istilted up vertically, the churning motion can'thappen. Tip the mixer as horizontally as possiblewithout spilling out the concrete.Using cooler water will extend the working time of themix. This will be helpful if you're in a very hotclimate. Every bagged concrete mix has a range ofwater requirements. Play it safe by adding less waterthan recommended, and then gradually add the remainingwater while keeping an eye on the consistency of themix.
