Effect of Temperature on Compressive Strength

Purpose: To investigate the effect of temperature on the compressive strength of consolidated samples composed of 10% clay and 160-mesh quartz sand.
Results: As shown in Figure 6, when the control agent was added at a specified concentration, the compressive strength of the consolidated sand body did not increase monotonically with temperature, but rather exhibited a trend of first increasing and then decreasing. The sand consolidation fluid demulsified at temperatures above 60°C, while the compressive strength exceeded 3 MPa under these conditions.

研究目的：探究温度对由10%黏土与160目石英砂构成的固结试样抗压强度的影响。
研究结果：如图6所示，当以指定浓度添加调控剂时，固结砂体的抗压强度并非随温度呈单调递增趋势，而是呈现先升后降的变化规律。当温度高于60℃时，固砂液会发生破乳，且在此条件下试样的抗压强度可超过3 MPa。
