Effect of Coarse Aggregate Characteristics on Drying Shrinkage of Concrete [PDF]

open access: yesEngineering and Technology Journal, 2008
Concrete is a composite material, consisting, mainly, of three phases: coarseaggregate, cement mortar, and the interface zone between them. The characteristicsof the interface zone largely govern the bond between cement paste or mortar andaggregate.

Government spending composition, aggregate demand, growth, and distribution [PDF]

open access: yesReview of Keynesian Economics, 2017
We study a demand-driven growth and distribution model with a public sector, both without and with government debt. Government spending is used to finance the accumulation of public capital and to pay wages to public employees. The interaction between public capital and induced technical change makes long-run growth: (i) hump-shaped in the composition ...
