Geomaterials as construction aggregates: a state-of-the-art
2021年11月22日 It refers to the ability of aggregate source rock to withstand destructive forces from various environmental conditions (such as cyclic changes of water content, freezing/thawing, salt crystallization, temperature changes, etc.) and from various types of mechanical loads related to prevalent modes of end-use.
Distribution of water-stable aggregates under soil tillage
2019年6月18日 Purpose Soil aggregates are the basic units of soil structure. Water-stable aggregates (WSAs) are greatly influenced by tillage practices. The main objective of our study was to assess the effects of different tillage practices on water aggregate stability on hillslope cropland in northern China and to identify the relationship between soil
Soil aggregates as massively concurrent
2017年4月14日 Full size table. Figure 1. Evolutionary change in soil aggregates: the life cycle of a soil aggregate microbial ‘incubator’ (meaning a compartmentalized microbial habitat). ( a) Depicts the
Water Demand of Concrete Recycled Aggregates
2015年1月1日 Water demand of recycled concrete aggregates of highest quality (RCA1 – lowest crushing indicator) is almost three times smaller than the water demand of the weakest aggregates (RCA11). Figure 2 presents the comparison of NCA and RCA water demand indicators with their identical granulation. Fig.
Use of ceramic wastes as aggregates in concrete
2021年11月1日 Rashid et al. [80] observed an exceptionally high water absorption of 17.39% in aggregate obtained from damaged sanitary ware waste. In the case of tile waste-based aggregate, the water absorption usually ranged from 2.52 to 7% and from 0.55 to 8.93% for fine and coarse aggregate, respectively [21, 24, 25, 29, 43, 57, 66].
Natural Aggregate an overview ScienceDirect Topics
Natural Aggregates: Coarse aggregates that will be used is siliceous/calcareous aggregates with a maximum size of 20 mm (3/4 inch) and specific gravity of 2.697 kg/m 3. These aggregates will be supplied from Lafarge quarry in Montreal, Canada. The water absorption of the aggregates was 0.6%.
Effects of Subsurface Drip Irrigation on Water
2021年2月3日 jointing and branching stages were the key stages for alfalfa water requirement. The water consumption had varied greatly (from 130 to 170mm) during the growth period of each alfalfa crop. The water consumption during the whole growth period was approximately 500mm, and the maximum water consumption intensity was

Modes of Greenhouse Water Savings ScienceDirect
2016年1月1日 From this open-air water intake, the four modes of greenhouse water savings are factored in to yield the total water usage in a greenhouse. This figure can then be compared to the irrigation requirements for open-air crops—as depicted in Figure 2—to obtain the percentage of water that a greenhouse can save.
