Experimental study on mechanical behavior of basalt fiber reinforced cemented soil subjected to complex environment in season frozen zone
In the seasonal frozen area, the freezing-thawing cycles and the erosion of the external environment are the main factors affecting the strength of cemented soil. It is an important topic to explore the development law of mechanical properties of cemented soil subjected to the complex environment in the seasonal frozen area and how to improve its mechanical properties. In this paper, a series of unconfined compressive strength tests, freezing-thawing cycle tests, salt freezing tests were carried out to analysis the influence of fiber content and fiber length on the mechanical properties of cemented soil. And then the influence of curing temperature, curing time, number of freezing-thawing cycles, salt freezing environment on the mechanical properties of basalt fiber reinforced cemented soil was discussed. The results show that the strength of basalt fiber reinforced cemented soil presents a generally convex curve with the increasing of fiber length, and the curve finally tends to the strength of cemented soil without fiber under the same fiber contents. It shows that the fiber distribution uniformity and fiber distribution density have great influence on the strength. The strength of basalt fiber reinforced cemented soil presents a wavy curve with the increasing of fiber content, the second wave peak value is less than the first wave peak value and the curve finally tends to a fixed value under the same fiber length. As the number of freeze-thaw cycles increased，the strength of the fiber-reinforced cemented soil tended to decrease． The strength of cemented soil without fiber decreased the most． The relationship between the strength and the number of freeze-thaw cycles was linear. Under the same number of freezing-thawing cycles, the damage degree of basalt fiber reinforced cemented soil is sulfate-freezing > mixed salt freezing > chloride salt freezing > water freezing. The research shows that the addition of basalt fiber can not only improve the mechanical properties of cemented soil, but also improve the resistance to the influence of complex environment such as freezing-thawing and salt freezing. The study in this paper can provide some reference for the application of basalt fiber reinforced cemented soil in the complex environment of seasonal frozen area.

Retrofitting diesel-powered construction equipment for clean construction in Hong Kong
Construction equipment is the power house in construction of buildings and infrastructure projects as many activities, such as land preparation and excavation, foundation works, installation works, concrete works, mainly rely on heavy equipment for implementation. However most construction equipment items are diesel powered and emit toxic pollutants of particulate matters (PM), Nitrogen oxides (NOx), unburned hydrocarbons (HC), carbon monoxide (CO), which are important sources of air pollutions detrimental to the health of construction workers and the general public near the site. This study briefly summarizes the available retrofitting and emission reduction technologies of diesel engines in terms of their affordability, effectiveness, technology maturity, services and support through literature review and analysis, and then applies selected retrofitting technologies to the current in-service construction equipment and evaluate their cost benefits through life cycle analysis on selected construction equipment from a large general contractor in Hong Kong. Recommendations are made on how the government can provide supports and inventive to the contractors so that the main contractors can take progressive actions to retrofit and upgrade of their equipment fleet to achieve clean construction in project development, while in the same time, operate with a viable financial plan to reduce its impact on project budget.
