Mechanistic insights across curing regimes for enzymatic and biopolymer‐optimized reinforcement in rock masses

Deep Underground Science and Engineering, EarlyView.
This study examines the effects of curing temperature on the mechanical behavior of underground rock masses treated with enzyme‐induced calcite precipitation (EICP) and an innovative biopolymer‐modified EICP (BP‐EICP). Abstract Biocementation is an innovative and sustainable technique for reinforcing weak and weathered rock masses in natural and ...

Soil pH Variation Within a Soil. III. pH Variation in Limed Soil

Communications in Soil Science and Plant Analysis, 2004
Abstract There are many methods for determining lime requirement, but no single method is suitable for all soils. A fast and efficient method to evaluate lime effect is needed. Soil buffering capacity tests and column-leaching tests were applied to the limed Van Rockel soil at the depth of 0–30 cm to evaluate pH distribution after liming. Two groups of

Soil pH Variation Within a Soil. II. pH Variation in a Neutral and an Alkaline Soil

Communications in Soil Science and Plant Analysis, 2004
Abstract Soil pH variation exists in particles of every kind of soils, including alkaline soil. The objective of this study was to examine soil pH varia-tion in a neutral and an alkaline soil using the column-leaching method. Column-leaching tests were applied to two soils (Callaway and Mount Palomar) at the depths of 0–30 and 30–60 cm.

In situ measurement of soil pH

Journal of Archaeological Science, 2004
Soil pH is one of the most important factors affecting the in situ preservation of archaeological artefacts of e.g. bone, shells and iron. It is therefore important to have good, reliable methods for determining the pH. However, in all methods that involve sampling of soil or water, loss of gaseous species such as carbon dioxide from the samples as ...

Mapping Soil pH

Soil Science Society of America Journal, 2005
The theoretical profitability of variable rate (VR) lime management has driven adoption of intensive soil sampling strategies used with complex statistical techniques without demonstration of approach efficacy. Our objective was to compare the accuracy of spatially continuous pH and lime requirement (LR) maps derived from ...

pH Tests on Soils

Proceedings of the Prehistoric Society, 1987
pH tests were carried out on eight soil samples taken from the site at the time of excavation. These were prepared and processed according to Black 1965, 922-923. Locations of the samples and the results showing the soils to be acidic are given below. All the samples were taken from the medium brown sandy loam (fig. 4).

Adopting a Robotic pH Instrument for Soil and Soil-Buffer pH Measurements in a Soil Test Laboratory

Communications in Soil Science and Plant Analysis, 2011
Optimum software settings were evaluated to minimize time of analysis without sacrificing data quality on an AS-3010D LabFit robotic instrument. There was little to no difference between soil and soil-buffer pH values measured via manual methods and LabFit analysis with four software settings. A setting for routine laboratory analysis was determined by

Interrelations between soil pH measurements in various electrolytes and soil solution pH in acidic soils

Australian Journal of Soil Research, 1991
Ninety soil samples (81 surface, 9 subsurface) were collected from eastern Queensland and soil pH (1:5 soi1:solution) was measured in each of deionized water (pH,), 0.01 M CaCl2, 0-002 M CaCl2 and 1 M KCl. Soil solution was extracted from each soil after incubation for 4 days at the 10 kPa matric suction moisture content, and pH (pHss) and electrical ...

Effect of pH on the sorption of uranium in soils

Journal of Environmental Radioactivity, 2001
This work was undertaken to study the influence of soil type and chemical composition on uranium sorption ratios (SR in 1 kg-1) in order to reduce the uncertainty associated with this parameter in risk assessment models. Thirteen soil samples were collected from three different locations in France under different geological conditions.
