Reuse of construction waste: performance under repeated loading

The use of recycled aggregates has increased greatly over the last decade owing to enhanced environmental sensitivities. The level of performance required by such materials is dependent upon the applications for which they are used. Many recycled construction wastes have adequate shear strength in relation to various geotechnical applications. However, a possible drawback of these materials is the risk of crushing during repeated loading. The work reported in this paper examined two waste materials: crushed concrete and building debris, both regarded as construction wastes. Tests were also performed on traditionally used crushed rock, in this case basalt. The materials were subjected to repeated loading in a large direct shear apparatus. The amount of crushing was quantified by performing particle size analysis of the tested material. The results have shown that both recycled construction wastes were susceptible to particle crushing. The amount of crushing was influenced by both the vertical pressure and the number of loading cycles. This leads to a marked decrease in peak friction angle

Sporting with the Classics: The Latin Poetry of William Dillingham (2010) (back cover)

Dana Sutton, University of California:
‘The great merit of Estelle Haan's study is that she is willing to take Dillingham seriously as a poet. Her reproduction of his work, together with an English translation and very detailed studies of his individual poems have the combined effect of rescuing an interesting poet from near-total oblivion. This, in my opinion, is the finest thing a neo-Latin scholar can do, and Haan accomplishes her task with the same skill, sensitivity, and eloquence that have distinguished her studies of other neo-Latin poets of this period (Joseph Addison and Vincent Bourne). It is impossible not to react to this volume with extreme respect and appreciation’.

Gordon Campbell, University of Leicester:
‘Nothing substantial has ever been published on Dillingham, but with this volume we have a new corpus of poetry that intersects with the work of many other seventeenth-century neo-Latin and vernacular poets. Professor Haan’s scholarship is here (as always) placed at the service of the poet, and she leads the reader gently through the work of a new poet. Professor Haan is the most eminent and able neo-Latinist of her generation, and her scholarship never fails; sometimes it dazzles as in the chapters on the hangman's stone and on Renaissance topiary. Her research is always up-to-date, and her translations have a gracefulness that other laborers in the vineyard can only envy’.
