(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: There is renewed effort in the construction sector to reduce CO2 emissions through the use of alternative binding materials to conventional Portland cements. Among the alternatives are phosphate-based ... -
The growth and knot property implications of a single stage thinning regime for Pinus patula saw log stands
(Stellenbosch : Stellenbosch University, 2019-03)ENGLISH ABSTRACT: The objective of the study was to analyse the growth and knot property implications of changing from the conventional two-stage thinning regime in Pinus patula saw log stands to a single stage mid-rotation ... -
Managing lumber stiffness variation in a sawmill : a statistical quality control approach
(Stellenbosch : Stellenbosch University, 2019-01)ENGLISH ABSTRACT: Several studies over the past two decades in South Africa showed that graded structural lumber from certain young pine resources did not conform to the stiffness requirements of SANS 10163- 1(2003). The ... -
Variation in root biomass for clonal eucalypts as a function of regime and site quality
(Stellenbosch : Stellenbosch University, 2019-03)ENGLISH ABSTRACT: The South African forestry industry may reduce imposed carbon taxation by accounting for the industry’s carbon sequestration. This study investigates the potential of Eucalyptus grandis x urophylla root ... -
The longevity of decaying eucalyptus hybrid roots in sub-tropical plantation forests
(Stellenbosch : Stellenbosch University, 2019-02)ENGLISH ABSTRACT: The global threat posed by extreme climate change has led to an increase in the amount of climate change related research. It is now more important than ever before to accurately quantify the carbon ... -
Chemical properties of thermally degraded E. dunnii and E. macarthurii
