,混凝土配合比要保證混凝土有良好的工作性能,比如可泵性、大流動(dòng)性、自密實(shí)性等。要滿(mǎn)足工程結構物強度、耐久性及其他特別設計要求?;炷猎谂浜媳仍O計中要積極合理應用減水劑等混凝土外加劑,以減少混凝土用水量,降低水膠比,提高混凝土強度。在混凝土中適量摻加粉煤灰、礦粉等外摻料,取代部分水泥和部分細骨料,在保證混凝土強度等級與工作性能要求下,可以顯著(zhù)提高混凝土的密實(shí)性,增加對鋼筋的保護作用,同時(shí)降低混凝土經(jīng)濟成本。
First of all, the concrete mix proportion should ensure that the concrete has good working performance, such as pumpability, large fluidity, self compacting, etc. To meet the engineering structure strength, durability and other special design requirements. In the mix proportion design of concrete, the concrete admixtures such as superplasticizer should be actively and reasonably applied to reduce the water consumption of concrete, reduce the water binder ratio and improve the strength of concrete. Adding high quality fly ash, mineral powder and other admixtures in concrete to replace part of cement and part of fine aggregate can significantly improve the compactness of concrete, increase the protection of reinforcement and reduce the economic cost of concrete under the condition of ensuring the strength grade and working performance of concrete.
其次,全自動(dòng)上料攪拌一體車(chē)原材料的管理要加強,砂、石料場(chǎng)要有良好的排水設施,以免底部積水。水泥、粉煤灰等粉料倉要有防潮、防雨措施。砂石料按品種、規格分隔堆放,避免混料。各種材料要標識清楚,特別是水泥、粉煤灰筒倉、外加劑貯存倉等進(jìn)料口要加蓋標識,專(zhuān)人管理,以防止進(jìn)錯料或受污染。
Secondly, the management of raw materials of the full-automatic feeding mixer should be strengthened, and the sand and stone yards should have good drainage facilities to avoid water accumulation at the bottom. Moisture proof and rainproof measures shall be taken for cement and fly ash silos. Sand and stone materials shall be stacked separately according to varieties and specifications to avoid mixing. All kinds of materials shall be clearly marked, especially the cement, fly ash silo, additive storage bin and other feeding ports shall be stamped with marks, and managed by special personnel, so as to prevent wrong feeding or pollution.
全自動(dòng)上料攪拌一體車(chē)能夠加快施工進(jìn)度、減少環(huán)境污染、改善施工條件、提高工程質(zhì)量和節約材料成本。但是,全自動(dòng)上料攪拌一體車(chē)的質(zhì)量控制也是不可遺漏的要點(diǎn)。
Full automatic feeding mixer truck can speed up the construction progress, reduce environmental pollution, improve construction conditions, improve project quality and save material cost. However, the quality control of fully automatic feeding mixer truck is also an important point.
全自動(dòng)上料攪拌一體車(chē)控制質(zhì)量的方法就是上面這些,希望現在建的各大工程都能保質(zhì)保量的完成。
The way to control the quality of full-automatic feeding mixer truck is the above. I hope all the major projects built now can be completed with quality and quantity guaranteed.
為全自動(dòng)上料攪拌一體車(chē)選擇的發(fā)動(dòng)機一定要馬力足,因為它要帶動(dòng)取力器、液壓油泵、減速機來(lái)進(jìn)行攪拌罐的運作。另一方面還要提供給底盤(pán)動(dòng)力,馬力不足是不行的。
The engine selected for the full-automatic feeding mixing truck must be of sufficient horsepower, because it needs to drive the power take-off, hydraulic oil pump and reducer to operate the mixing tank. On the other hand, we have to provide power to the chassis. We can't do without enough horsepower.
變速箱這里陜齒法士特的,在國內到處可以看到它的廠(chǎng)房和變速箱物流運輸車(chē);小型混凝土攪拌車(chē)選發(fā)動(dòng)機馬力可以稍小一點(diǎn),因為工作強度沒(méi)那么大,夠用就行,但是不能太小,太小買(mǎi)到手里一樣不省油、耽誤事。
The gearbox of Shaan tooth fast is recommended here, and its workshop and gearbox logistics vehicles can be seen everywhere in China; Small concrete mixer engine horsepower can be slightly smaller, because the work intensity is not so big, enough on the line, but not too small, too small to buy the hand is not fuel saving, delay.
