【摘要】：高性能混凝土（High Performance Concrete簡(jiǎn)稱HPC）是在20世紀(jì)80年代末90年代初，部分發(fā)達(dá)國(guó)家提出的一種以結(jié)構(gòu)耐久性為主要設(shè)計(jì)指標(biāo)，全新概念的新型混凝土，它是在傳統(tǒng)混凝土原有性能的基礎(chǔ)上給以大幅提升，采用現(xiàn)代混凝土工藝制作的混凝土。高性能混凝土至今已經(jīng)在很多高層建筑、橋梁工程、海港建筑、道路工程等重要工程中應(yīng)用,發(fā)揮出其獨(dú)特的優(yōu)越性。 本文主要研究以下幾個(gè)方面的內(nèi)容:(1)高性能混凝土的誕生背景、研究現(xiàn)狀、發(fā)展方向和應(yīng)用現(xiàn)狀；(2)高性能混凝土的配合比設(shè)計(jì)原則、設(shè)計(jì)方法與設(shè)計(jì)實(shí)例；(3)高性能混凝土施工中存在的問題分析、高性能混凝土施工質(zhì)量控制的措施；(4)高性能混凝土在福建閩南地區(qū)的應(yīng)用，主要以泉州瀾湖郡1#、2#、3#樓為工程實(shí)例，通過配合比設(shè)計(jì)方案比選，證明高性能混凝土摻入粉煤灰和高效減水劑的重要性，通過在施工過程中該注意的施工技術(shù)要點(diǎn)，達(dá)到施工質(zhì)量控制的效果。 通過調(diào)研、查閱大量資料及實(shí)證，結(jié)果表明：（1）高性能混凝土具有普通混凝土所無法比擬的優(yōu)越性，，高性能混凝土具有更好的工作性、耐久性和穩(wěn)定性，同時(shí)能夠更多地利用工業(yè)廢渣及其它廢棄物；（2）可以在鋼筋混凝土施工中采取各種特殊措施進(jìn)行防腐處理，以提高結(jié)構(gòu)的耐久性和使用壽命；（3）在配置上的特點(diǎn)是采用低水膠比，選用優(yōu)質(zhì)原材料，且必須加入足夠數(shù)量的摻合料和高效外加劑。高性能混凝土具有良好的經(jīng)濟(jì)指標(biāo)和環(huán)保意義，是今后混凝土技術(shù)的發(fā)展方向。通過本文研究，對(duì)高性能混凝土在實(shí)際工程的應(yīng)用，特別是對(duì)于在福建閩南地區(qū)高性能混凝土的應(yīng)用具有一定的參考價(jià)值。
[Abstract]:High performance Performance Concrete (HPC) is a new type of concrete, which is proposed by some developed countries in the late 1980s and early 1990s, which takes structural durability as the main design index and a new concept. Based on the original performance of traditional concrete, it is made by modern concrete technology. High performance concrete (HPC) has been used in many high-rise buildings, bridges, seaports, road engineering and other important projects, giving play to its unique advantages. This paper mainly studies the following aspects: 1) the background of the birth of high performance concrete, the present research situation, the development direction and the application situation of high performance concrete (2) the design principle of mix ratio of high performance concrete. Design method and design example: analysis of the problems existing in the construction of high performance concrete, the measures for quality control of high performance concrete construction and the application of high performance concrete in the south of Fujian Province, mainly taking the #2 #2# Building of Quanzhou Lanhu County as an engineering example. The importance of mixing high performance concrete with fly ash and high efficiency water reducer is proved by comparing and selecting the design scheme of mix ratio. The effect of quality control is achieved through the key points of construction technology which should be paid attention to in the construction process. Through research, consulting a large number of data and empirical evidence, the results show that high performance concrete has more advantages than ordinary concrete, and high performance concrete has better workability, durability and stability. At the same time, it can make more use of industrial waste slag and other waste materials. It can take various special measures in reinforced concrete construction for anticorrosive treatment to improve the durability and service life of the structure. Select high-quality raw materials and must add enough admixtures and high-efficiency admixtures. High performance concrete has good economic index and environmental protection significance, which is the development direction of concrete technology in the future. Through the research in this paper, it has certain reference value for the application of high performance concrete in practical engineering, especially for the application of high performance concrete in the south of Fujian province.
