研究結果表明: 1太白山南坡土壤的主要理化性質隨海拔高度的上升呈有規律的變化:隨海拔高度上升,機械組成由粉粒砂粒粘粒逐漸過渡到砂粒粉粒粘粒,海拔1600m以下出現粘化層;土壤有機質豐富,表層有機碳含量一般在20g kg以上,有機碳含量隨海拔高度升高而相應增加,海拔3500 3700m的灌叢草甸植被下有機碳含量最高;土壤呈酸性或微酸性,並隨海拔上升, ph值略微降低,酸性增強,海拔2700m以上的土壤多呈鹽基不飽和狀態,表明土壤淋溶作用較強, ph值和鹽基飽和度呈極顯著正相關;土體與粘粒中的sio _ 2 、 al _ 2o _ 3 、 fe _ 2o _ 3含量相對比較穩定,土體中sio _ 2含量較高, cao含量較少, sio _ 2 、 al _ 2o _ 3和fe _ 2o _ 3含量之和約占土壤礦質部分的92 ,礦質元素含量的順序依次為: sio _ 2 al _ 2o _ 3 fe _ 2o _ 3 k _ 2o mgo cao tio _ 2 mno 。The expansion agents can only make up the shrinkage to some extent, and the compensation effects would be reduced when the retardener and fly - ash are used. the expansion agents are not panaceas to avoid the shrinkage cracking as expansion can also reduce the concrete soundness. under bad curing condition, the polypropylene fibrillated film fiber can improve concrete ' s anti - crarking property, while the nominal steels have very unobvious effects. to reduce the concrete shrinkage thus avoid the cracking, the former factors must all be taken into account in concrete proportion design to develop sound concrete
研究結果表明,水泥的品種和用量是影響混凝土收縮值的主要因素之一,當混凝土中水泥用量超過470kg / m ~ 3時,混凝土的收縮值超過400 10 ~ ( - 6 ) ,在約束狀態下存在高開裂風險;採用細砂使混凝土單位用水量顯著提高,收縮值也大幅增加;優質粉煤灰總體上能抑制混凝土的收縮,以超量方式摻入其抑制作用更加明顯,但粉煤灰混凝土早期的粘聚性較差,應注意養護,以免失水產生龜裂;早強減水劑和緩凝減水劑都會使混凝土收縮值增加;膨脹劑只能補償混凝土部分收縮,同時受緩凝劑和粉煤灰的抑制,而且膨脹使混凝土的體積安定性增加了不確定因素,膨脹劑不是解決混凝土收縮裂縫的良方。This article researches the blown - out concrete technology with reduced slag and fly ash from refining of magnesium in pidgeon technics as its main raw materials, which can quite eliminate the solid contamination during the magnesium producation and use up fly ash partly ; it is of great signficance for the development of clean magnesium industry
