Slope protection components made of sandy soil

cement

and a stabilizer named SY were investigated.Unconfined compressive strength and freeze-thaw cycle tests were carried out by samples with maximum dry density.Results present that all the engineering properties of the stabilized soil samples are improved significantly and SY stabilizer

cement

and sandy soil have coordination.From SEM pictures and mechanism analyzes

it can be proved that for sandy soil which has more pores in micro-structure

AFt Crystals

SiO2 gel

and C-S-H gel fill pores well

which makes the micro-structure denser and the expansion of AFt Crystals.They all benefit macro-engineering properties of stabilized sandy soil.SY solidified soil components satisfy the quality requirements in slope protection engineering and have high economic

social

and ecological values.
