In order to study effects of temperature fluctuation on strength characteristics and destruction characteristics of cement-stabilized soils

samples of cement-stabilized soils which are made of two kinds of plain soils are made with rate of contents plain soils: cement: water egual to 40:6:3 and are conserved under 25°C±2°C

10°C±2°C

0°C± 2°C

whereafter their uniaxial compressive strength are mensurated and their breakage characteristic are observed.The study′s findings indicate: influence of temperature fluctuation on peak strains decreases as the stadium increases;when the stadium（within 1

4

day） is shorter

the uniaxial compressive strength of cement-stabilized soils doesn′t vary markedly accompanying with temperature variety

while 7

advancing protected temperatures influences on their strength exaltation;accompanying with temperature heating up

the uniaxial compressive strength of cement-stabilized soils is rising obviously

while the trend of growth is more and more slow-moving;under the low temperature the uniaxial compressive strength of cement-stabilized clay is lower than the uniaxial compressive strength of cement-stabilized silt

but once the curing temperature rises

the uniaxial compressive strength of cement-stabilized clay will exceed the uniaxial compressive strength of cement-stabilized silt;under the low curing temperature cement-stabilized soils are apt to express obvious brittleness breakage and quick to produce cracks.
