摘 要: 膠凝砂礫石是一種介于混凝土與堆石料之間的新型筑壩膠凝材料,具有節(jié)約資源、降低造價、保護環(huán)境等優(yōu)點，對膠凝砂礫石材料的特性研究是壩體結(jié)構(gòu)設計的關(guān)鍵，目前對于膠凝砂礫石材料的特性研究缺少較為全面的認識。為使膠凝砂礫石材料更好的應用于實際工程，因此通過文獻查閱，本文總結(jié)了膠凝砂礫石材料的力學性能和凍融環(huán)境下的材料耐久性等方面試驗研究，對膠凝砂礫石材料特性受膠材用量、單位用水量、水膠比、砂率、齡期等多種參數(shù)的影響規(guī)律進行綜合分析，為膠凝砂礫石筑壩材料的進一步研究和應用提供理論基礎。

Abstract: Cementitious sand and gravel is a new type of dam cementing material between concrete and rockfill. It has the advantages of saving resources, reducing cost and protecting environment. The study of the characteristics of  cementitious sand and gravel materials is the key to the design of dam structure. At present, there is a lack of comprehensive understanding of the characteristics of  cementitious sand and gravel materials. In order to make the cementitious sand and gravel material better applied to practical engineering, through literature review, this paper summarizes the mechanical properties of cementitious sand and gravel materials and the durability of materials under freeze-thaw environment are summarized, and the characteristics of cementitious sand and gravel materials are comprehensively analyzed by the influence of various parameters such as rubber dosage, unit water consumption, water-glue ratio, sand rate, age, etc.,so as to provide a theoretical basis for further research and application of cementitious sand and gravel damming materials.

 

Keywords: cementitious sand gravel; material science; mechanical properties; durability
