    摘??要:將改性后的廢舊橡膠顆粒加入到抹面砂漿中,不僅可提高廢橡膠的利用率、減小環境污染,還可以利用橡膠顆粒的特有性能,改善傳統抹面砂漿的缺陷,提高抹面砂漿的韌性、抗凍融性能和抗沖擊性能。研究表明,橡膠顆粒的加入會降低抹面砂漿的強度和彈性模量,但抹面砂漿對強度的要求不高,故橡膠顆粒在抹面砂漿中完全可以應用。Abstract:Puttingthemodifiedwastecrumbrubbertoaddinthesurfacemortarhasmanyadvantages,whichnotonlycanimprovetheutilizationratioofthewasterubber,decreasingenvironmentalpollution,butalsocanimprovethedefectsoftraditionalsurfacemortaraswellasthetoughness,anti-freezingandthawingperformanceandimpactresistanceofsurfacemortar.Thestudyresultsshowthatalthoughaddingrubberparticlescanreducestrengthandelasticmodulusofthesurfacemortar,itcanstillbeappliedinthesurfacemortarbecauseofthelowstrengthrequirementofthesurfacemortar.

    摘 要:使用未處理和處理后的鑄造廢砂取代天然砂制備混凝土,并對混凝土的性能作了對比分析。結果表明,與基準混凝土相比,用未處理的廢砂取代天然砂時,隨著取代率的提高,混凝土的流動性變差,抗壓強度也隨之降低;處理后的廢砂與未處理廢砂對混凝土性能的影響趨勢一致,抗壓強度有所提高,當僅取代天然砂中的細砂時,對混凝土的抗壓強度幾乎沒影響。 Abstract: The green concretes are prepared by using untreated and treated waste foundry sand to partially substitute the natural sands, and the performances of the two kinds of concretes were compared and analyzed. The test results show that comparing with the reference concrete, the liquidity and compressive strength of the concrete with untreated waste foundry sand decrease with the creasing the content of the waste foundry sand; the effect tendency of treated waste foundry sand on the performances of concrete are consistent with those of untreated waste foundry sand, and the performances have a certain improvement. When using all the treated waste foundry sand to replace the fine sand in natural sand, it’s found that treated waste foundry sand has hardly effect on the compressive strength of the concrete.

    摘 要:為突破當前碾壓混凝土壓實厚度只有30cm左右的限制,推動碾壓混凝土施工技術的發展,引進國外新型垂直碾壓設備和深層壓實度檢測儀器,通過兩次生產性試驗,對檢測儀器進行改進,確定了60cm厚層混凝土碾壓工藝,并成功應用于110m高碾壓混凝土雙曲拱壩局部壩段。 Abstract:The compaction thickness limit of the RCC is only 30cm at present. For breaking the thickness limit and promoting the development of RCC construction technology, the new vertical rolling equipment and deep compaction testing instruments are introduced from abroad. By doing the productive tests twice, the detecting instrument is improved, and concrete compaction technology for the 60cm compaction thickness is determined. The technology has successfully applied in the local dam section of 110m high roller compacted concrete hyperbolic arch dam.
