【摘要】：近年來,隨著城市建設的迅速發(fā)展,建筑能耗在世界能源總耗量中占有的比例日益增大,不僅嚴重污染了環(huán)境,而且制約了世界各國的可持續(xù)發(fā)展。為了解決能源危機,同時滿足城市建設的發(fā)展需求,就必須研制和推廣新型綠色墻體材料。當前,新型墻體的代表產(chǎn)品主要是復合墻體,它能夠最大限度地完成工業(yè)化生產(chǎn)和科學化管理,實現(xiàn)建筑節(jié)能,推進住宅產(chǎn)業(yè)化的進程。但由于板體自身過重的原因,目前已經(jīng)制約了這項新型墻體節(jié)能技術的發(fā)展。本文將通過pp纖維、聚合物、泡沫劑改性后的火山渣輕集料混凝土應用于復合保溫外掛墻板技術中,在滿足各方面性能要求的同時大大減輕了板體的重量,有效促進了該項技術的發(fā)展。具體的工作內容如下:(1)依據(jù)我國現(xiàn)行國家規(guī)范和地方標準,建立火山渣輕集料混凝土復合保溫外掛墻板的計算模型,并計算EPS保溫材料的厚度,使建筑節(jié)能率達到65%。通過有限元分析軟件的模擬計算和相關的力學計算論證了火山渣輕集料混凝土復合保溫外掛墻板結構設計的理論可行性;(2)研究纖維、聚合物、泡沫劑對火山渣輕集料混凝土性能的影響。在火山渣輕集料混凝土中單摻和混摻pp纖維、聚合物、泡沫劑三種改性物質,火山渣輕集料混凝土的抗壓強度和抗折強度提高,吸水率降低。在火山渣輕集料混凝土中摻植物秸稈纖維,可以提高火山渣輕集料混凝土的抗壓強度和抗折強度。將泡沫劑摻入火山渣輕集料混凝土中,導熱系數(shù)降低,改善了熱工性能;(3)研究建筑垃圾紅磚部分替代和完全替代火山渣對混凝土性能的影響。紅磚部分或完全替代火山渣制備混凝土,可以提高混凝土的基本力學性能和吸水率,降低混凝土的抗?jié)B性能和抗凍性能;(4)通過正交試驗設計和極差分析,研究pp纖維、聚合物、泡沫劑的摻量對火山渣輕集料混凝土基本力學性能和吸水率的影響。發(fā)現(xiàn)當pp纖維摻量為1.5‰、聚合物摻量為10%、泡沫劑摻量為0.1‰時,火山渣輕集料混凝土各方面性能最為理想,由此確定火山渣輕集料混凝土的最佳配合比;(5)采用最佳配合比的火山渣輕集料混凝土和基本配合比的火山渣輕集料混凝土進行抗氯離子滲透性能和抗凍性能對比試驗,發(fā)現(xiàn)改性火山渣輕集料混凝土的抗?jié)B性和抗凍性得到了很大提高;(6)采用SEM研究改性火山渣輕集料混凝土的微觀結構,發(fā)現(xiàn)pp纖維、聚合物、泡沫劑可顯著改善火山渣輕集料混凝土界面過渡區(qū)結構;(7)依據(jù)相關國家標準對采用最佳配合比的火山渣輕集料混凝土制備的復合保溫外掛墻板進行性能測試。發(fā)現(xiàn)墻板的物理力學性能和熱工性能均符合標準要求,可以應用于實際工程。
[Abstract]:In recent years, with the rapid development of urban construction, the proportion of building energy consumption in the total energy consumption of the world is increasing day by day, which not only pollutes the environment seriously, but also restricts the sustainable development of countries all over the world. At the same time, to meet the development needs of urban construction, it is necessary to develop and popularize new green wall materials. At present, the representative products of the new wall are mainly composite walls, which can maximize industrial production and scientific management. The development of this new wall energy saving technology has been restricted by the reason that the plate body itself is overweight. In this paper, pp fiber, polymer, The modified volcanic slag lightweight aggregate concrete is used in the composite insulation wall board technology, which can meet the performance requirements of various aspects and greatly reduce the weight of the plate body at the same time. The concrete work contents are as follows: 1) according to the current national and local standards of our country, the calculation model of volcanic slag lightweight aggregate concrete composite insulation wall board is established, and the thickness of EPS insulation material is calculated. Through the simulation calculation of finite element analysis software and related mechanics calculation, the theoretical feasibility of structural design of composite thermal insulation wall panel of volcanic slag lightweight aggregate concrete is demonstrated. The influence of foaming agent on the performance of volcanic slag lightweight aggregate concrete. The compression strength and flexural strength of volcanic slag lightweight aggregate concrete are improved by adding and mixing three modified substances, pp fiber, polymer and foam agent, The compressive strength and flexural strength of volcanic slag lightweight aggregate concrete can be improved by adding plant straw fiber into the volcanic slag lightweight aggregate concrete. The thermal conductivity of the volcanic slag lightweight aggregate concrete is reduced by adding foam agent into the volcanic slag lightweight aggregate concrete. The influence of partial substitution and complete substitution of red brick on concrete performance is studied. The basic mechanical properties and water absorption of concrete can be improved by using red brick partially or completely instead of volcanic slag to prepare concrete. To reduce the impermeability and frost resistance of concrete by orthogonal design and range analysis, PP fibers and polymers are studied. The effect of foaming agent content on the basic mechanical properties and water absorption of volcanic slag lightweight aggregate concrete is studied. It is found that when the content of PP fiber is 1.5 鈥，
