Based on the theory of unsaturated soil mechanics and the properties of compacted expansive soil, this paper takes the northern part k12 + 840 - k12 + 920 of nanning urban highway as an example to studies some aspects of lime improvement of expansive soil and the technology of construction. the chief content of this paper is : the lime improvement mechanism of expansive soil ; confirm the technical parameters of lime mixed from the results of test in laboratory ; the scale - down test to define the maximum effective grain size of expansive soil when it is improved by lime ; by building bank slope model and making use of finite element seepage flow program of saturated - unsaturated to calculate the examples, this paper simulates the humidity site in order to checkout the effect of lime improvement ; studies and proves that it is feasible to mix blocky expansive soil and pulverous lime, and to fill roadbed by common construction machines etc.
本文研究的工作就下述幾個方面展開：用石灰改良膨脹土的機理；通過室內試驗確定摻灰的技術指標；在室內進行膨脹土摻灰的最大有效粒徑的模擬試驗，即鈣離子水試驗，由此總結出「粉?塊」灰?土攪拌工藝的有效性、合理性和可行性；用數值方法對路堤使用期的濕度場進行模擬，並與路堤的強度?變形的計算域耦合，以檢驗土性改良的效果，從而探索一種描述改良膨脹土路堤運行工況的數值方法；用現有最常用的且費用最低的施工機具，對灰?土進行「粉?塊」攪拌摻和及路基的填築施工等。When fillings is other materials ( unprocessed montmorillonite, powder coal ash, co - composite of powder coal ash and organo - montmorillonite, co - composite ofcarbonizing calcium and organo - montmorillonite ) in the binder and content of organo - montmorillonite in the binder is five percent decided by tensile - shear experiment, tensile - shear strength of binder is up to tiptop ; at the same time, this paper carries out abrasion experiment, and, by comparison, concludes abrasion property of coating is optimum when content of organo - montmorillonite in the binder coating is five percent, and observes abrasion sample under set
當膠粘劑中填料為其它物質（未處理蒙脫土、粉煤灰、粉煤灰和有機化蒙脫土共復合、碳化鈣和有機化蒙脫土共復合）時，通過拉伸剪切試驗確定膠粘劑中有機化蒙脫土含量為5時，膠粘劑的拉伸剪切強度最高；同時進行了沖蝕磨損試驗，通過比較得出，當膠粘劑塗層中有機化蒙脫土含量達到5時，塗層的耐沖蝕磨損性能最佳，並對沖蝕磨損試樣在掃描電子顯微鏡（ set ）上進行觀察。Road foundations. high - calcium lime for soils and roads. specifications

土壤中鈣鎂總量表現為整體上石灰巖地區鈣鎂總量較砂頁巖地區含量高。Calcium - enriched fly ash debases the numerical value of critical strength of frozen injury and improves the microstructure because of its form effect, activity, tiny aggregate effect and self - hardening property. so it is feasible to make it an important component of minus - temperature concrete
因為增鈣粉煤灰具有形態效應、活性效應、微集料效應和自凝性、自硬性等優勢，它改善了混凝土的微觀結構，降低了負溫混凝土的抗凍臨界強度，所以增鈣粉煤灰可以作為負溫混凝土的摻合料。There is still a preference in certain areas and countries for burned lime as
相比重鈣石灰石，用燒石灰來調整土壤酸度The preliminary report of fertilizer application experiments on the recent reclaimed light sieroze
新墾淡灰鈣土不同施肥定位試驗初報Comparing with the reference concrete, the resistance of freezing - thawing cycles and chloride diffusivity in calcium - enriched fly ash concrete increase, because the pore structures and interface structure are optimized, so the durability of calcium - enriched fly ash concrete is perfect
相對于基準混凝土，增鈣粉煤灰混凝土的抗凍性和抗氯離子滲透性能均有所提升，這主要是由於增鈣粉煤灰改善了混凝土的孔結構和界面結構，從而使其具有更為優異的耐久性。Originally from green concrete and concreting in minus - temperature, the critical strength of frozen injury of minus - temperature calcium - enriched fly ash concrete and the rule of strength development are studied in this paper. through the test of resistance of freezing - thawing cycles and chloride diffusivity, the influence of curing system and calcium - enriched fly ash on the performance of concrete are studied ; and through the modern methods ( xrd, sem, and so on ), the hydration products, pore structures and microstructure are studied
本文既著眼于綠色混凝土，又致力於混凝土的負溫施工，研究了增鈣粉煤灰混凝土的抗凍臨界強度及其負溫抗壓強度發展規律;通過快凍試驗和氯離子滲透試驗，研究養護制度和增鈣粉煤灰摻合料對混凝土耐久性能的影響;並通過光學顯微鏡法、掃描電鏡和xrd等現代分析方法，研究負溫增鈣粉煤灰混凝土的水化產物、孔結構和顯微結構。分享友人
