【摘要】：環(huán)境問題一直備受關(guān)注，建筑業(yè)和陶瓷業(yè)迅猛發(fā)展成為國家經(jīng)濟(jì)收入的主要來源，快速發(fā)展的同時(shí)，也給我們的環(huán)境帶來了一定的污染，如何將污染降低到最低并合理利用取得一定的經(jīng)濟(jì)效益是防災(zāi)減災(zāi)領(lǐng)域的一個(gè)重要課題。 本研究從降低污染、保護(hù)環(huán)境和節(jié)約資源的角度出發(fā)，通過對陶瓷粉與水泥、粉煤灰的不同比例摻和性能進(jìn)行實(shí)驗(yàn)研究，合理利用陶瓷工業(yè)生產(chǎn)中產(chǎn)生的二次陶瓷粉為實(shí)驗(yàn)原材料，采用對比實(shí)驗(yàn)的方式，探討陶瓷粉在混凝土生產(chǎn)中的利用，降低水泥及混凝土等建筑用材的生產(chǎn)成本。通過將陶瓷拋光磚陶瓷粉粉與水泥、礦粉進(jìn)行對比實(shí)驗(yàn)確定其可以作為生產(chǎn)原料加入到混凝土制備中，結(jié)合混凝土的一系列力學(xué)實(shí)驗(yàn)分析對比研究發(fā)現(xiàn)： 1、實(shí)驗(yàn)陶瓷粉的燒失量、細(xì)度、含水量與礦粉相差不大，具有一定的潛在水硬性和火山灰活性，而且水泥膠砂強(qiáng)度活性指數(shù)可達(dá)89%，但比表面積、凈漿流動度遠(yuǎn)高于礦粉。 2、灼燒前后的陶瓷粉在標(biāo)準(zhǔn)稠度用水量、對水泥初凝時(shí)間和終凝時(shí)間有不同的影響，，與礦粉有著明顯的區(qū)別。 3、陶瓷粉摻入混凝土試塊后，力學(xué)特點(diǎn)與礦粉的表現(xiàn)不同，重點(diǎn)是不同齡期抗壓強(qiáng)度、劈裂抗拉強(qiáng)度和抗折強(qiáng)度。摻入適量的陶瓷粉有利于混凝土構(gòu)件的抗彎能力和抗折水平，在工程實(shí)際中可以減緩細(xì)小裂縫的擴(kuò)展速度，增強(qiáng)混凝土構(gòu)件的耐久性。 4、陶瓷粉中會含有氯離子成分，而氯離子對鋼筋侵蝕的影響沒有明確值，故在工程中的大范圍應(yīng)用還需要進(jìn)一步研究。
[Abstract]:Environmental problems have always been the focus of attention. The construction industry and ceramic industry have developed rapidly into the main source of national economic income. The rapid development has also brought about certain pollution to our environment. How to reduce the pollution to the lowest and obtain certain economic benefits is an important subject in the field of disaster prevention and mitigation. From the point of view of reducing pollution, protecting the environment and saving resources, the paper analyzes the ceramic powder and cement. The mixing properties of fly ash in different proportions were studied. The secondary ceramic powder produced in ceramic industry was used as the experimental raw material, and the use of ceramic powder in concrete production was discussed by means of comparative experiment. Reduce the production cost of building materials such as cement and concrete. By comparing ceramic polishing tile ceramic powder with cement and mineral powder, it is determined that the ceramic powder can be added to the preparation of concrete as raw material. In combination with a series of mechanical experiments of concrete, it is found that: 1. The fineness, water content and mineral powder have some potential hydration and pozzolanic activity, and the strength activity index of cement sand can reach 89, but the specific surface area. The fluidity of pure slurry is much higher than that of mineral powder. 2. The water consumption of ceramic powder before and after burning has different effects on the initial setting time and final setting time of cement, and it is obviously different from that of mineral powder. 3. After the ceramic powder is mixed into the concrete test block, the water consumption of ceramic powder before and after burning has different effects on the initial setting time and final setting time of cement. The mechanical characteristics are different from those of mineral powder, and the emphasis is on compressive strength, splitting tensile strength and flexural strength at different ages. The addition of proper amount of ceramic powder is beneficial to the flexural capacity and the level of bending resistance of concrete members, and can slow down the propagation speed of small cracks and enhance the durability of concrete members in engineering practice. However, the influence of chloride ion on steel bar erosion is not definite, so its wide application in engineering needs further study.
