Opis:
The process of care of soils stabilized with hydraulic binder affects the results of destructive and non- -destructive tests. The process itself depends on the country performing stabilization. This study investigated the effect of immersion of stabilized soil samples during the curing process on the ultrasonic pulse velocity. The study showed an increase in velocity of 12.9% in samples immersed in water for seven days. The paper presents test results for seven methods of soil treatment.

Opis:
Evaluating soil strength by geophysical methods using P-waves was undertaken in this study to assess the effects of changed binder ratios on stabilization and compression characteristics. The materials included dredged sediments collected in the seabed of Timrå region, north Sweden. The Portland cement (Basement CEM II/A-V, SS EN 197-1) and ground granulated blast furnace slag (GGBFS) were used as stabilizers. The experiments were performed on behalf of the Svenska Cellulosa Aktiebolaget (SCA) Biorefinery Östrand AB pulp mill. Quantity of binder included 150, 120 and 100 kg. The properties of soil were evaluated after 28, 42, 43, 70, 71 and 85 days of curing using applied geophysical methods of measuring the travel time of primary wave propagation. The P-waves were determined to evaluate the strength of stabilized soils. The results demonstrated variation of P-waves velocity depending on stabilizing agent and curing time in various ratios: Low water/High binder (LW/HB), High water/Low binder (HW/LB) and percentage of agents (CEM II/A-V/GGBFS) as 30%/70%, 50%/50% and 70%/30%. The compression characteristics of soils were assessed using uniaxial compressive strength (UCS). The P-wave velocities were higher for samples stabilized with LW/HB compared to those with HW/LB. The primary wave propagation increased over curing time for all stabilized mixes along with the increased UCS, which proves a tight correlation with the increased strength of soil solidified by the agents. Increased water ratio gives a lower strength by maintained amount of binder and vice versa.

Opis:
The pullout behavior of mechanically stabilized earth (MSE) structures is very complicated and depends on many parameters which related to the backfill soil properties, the reinforcement characteristics and the interaction between them. This paper investigates the pullout behavior of many soil reinforcements under static and repeated loading. Four types of steel reinforcements were studied: Strip, W-shaped, ribbed and punched. The results obtained show that the change of the shape of reinforcement may improve the pullout resistance of MSE structures. Therefore, the best performance was obtained by the ribbed and the punched reinforcements, under static loading as well as repeated loading.
