underlying cement-stabilized road section was performing adequately The study concluded that cement stabilization using the FDR approach is a viable option for improving some unpaved roads It can be particularly attractive in situations where placement of conventional cement-treated aggregate is impractical because of time constraints on ....

Generally, the more granular materials are used because they pulverize and mix readily and require the least amount of cement Waste and sub-standard materials found at aggregate plants, old gravel road and street materials, as well as cinders and slag, make excellent soil cement, if they contain 55 percent or more gravel passing the No 4 sieve...

Bikemandan, Portland Cement PC will not give any advantage as far as keeping the floor dry PC loves to hold onto water and this is why it will mold The best material to use for keeping an earthern floor dry is Magnesium Phospate, which is more expensive than PC but at the ratios needed for an earthen floor, it could be do-able...

Water/cement ratio theory states that for a given combination of materials and as long as workable consistency is obtained, the strength of concrete at a given age depends on the w/c ratio The lower the w/c ratio, the higher the concrete strength All materials used for a design including the water quality should be to a high standard...
