隨著時代的開展和開展新農村建設的要求，現代化建設中房屋混凝土質量逐漸被人重視起來，以往的人力攪拌和半機械攪拌設施、施工效率慢而且攪拌不均勻導致混凝土質量不過關、從而影響到房屋質量。面對鄉村修建市場這種狀況、鼎峰三民研發出混凝土輸送泵、不(bu)僅大大節省了人力成本而(er)且混(hun)(hun)凝土質量達(da)到(dao)商品混(hun)(hun)凝土的(de)(de)要(yao)(yao)求，加(jia)上汽(qi)車運送(song)(song)(song)(song)(song)、不(bu)受(shou)空(kong)間(jian)限(xian)制、具有移動轉場快(kuai)的(de)(de)特(te)點。混(hun)(hun)凝土輸(shu)送(song)(song)(song)(song)(song)泵(beng)(beng)泵(beng)(beng)送(song)(song)(song)(song)(song)砼(tong)是混(hun)(hun)凝土拌合料(liao)在泵(beng)(beng)送(song)(song)(song)(song)(song)推動下(xia)沿著輸(shu)送(song)(song)(song)(song)(song)管進(jin)行輸(shu)送(song)(song)(song)(song)(song)和(he)澆(jiao)筑的(de)(de)，因此(ci)砼(tong)不(bu)但要(yao)(yao)滿足設計規定(ding)的(de)(de)強(qiang)度，耐(nai)久性等要(yao)(yao)求，還要(yao)(yao)滿足管道(dao)輸(shu)送(song)(song)(song)(song)(song)要(yao)(yao)求，砼(tong)拌合料(liao)能夠順(shun)利通(tong)過管道(dao)，摩擦阻(zu)力小，不(bu)離析，不(bu)阻(zu)塞，可泵(beng)(beng)性好(hao)。對于初次使(shi)用混(hun)(hun)凝土輸(shu)送(song)(song)(song)(song)(song)泵(beng)(beng)的(de)(de)新用戶，應(ying)該不(bu)會產生阻(zu)塞，泵(beng)(beng)送(song)(song)(song)(song)(song)性能好(hao)的(de)(de)砼(tong)拌合料(liao)，這樣可以使(shi)操作人員能盡快(kuai)熟悉泵(beng)(beng)機(ji)的(de)(de)性能。細(xi)粉(fen)料(liao)含0.25mm以下(xia)的(de)(de)細(xi)粉(fen)料(liao)及水(shui)泥，總(zong)重量必須達(da)到(dao)400KG每立方米，這樣的(de)(de)配置(zhi)的(de)(de)砼(tong)拌合料(liao)即使(shi)含有碎石，一(yi)般也容易泵(beng)(beng)送(song)(song)(song)(song)(song)出去。請記住，在泵(beng)(beng)送(song)(song)(song)(song)(song)混(hun)(hun)凝土之前應(ying)先泵(beng)(beng)0.5-0.8每立方米水(shui)泥砂漿。砼(tong)拌合物是由(you)多種成分組成，合理的(de)(de)選(xuan)擇砼(tong)的(de)(de)配比是獲得良好(hao)的(de)(de)泵(beng)(beng)送(song)(song)(song)(song)(song)性能的(de)(de)關鍵(jian)。

砼拌合(he)料的可泵(beng)性主(zhu)要取決于(yu)三個重要因(yin)素：

1.骨料的構成(cheng)和(he)骨料的級配。

 2.細粉料(liao)的(de)含量，就是料(liao)的(de)直徑為0.25mm以下的(de)物(wu)料(liao)包括水泥和天然(ran)超(chao)細粉料(liao)的(de)含量，

3.水(shui)灰(hui)和坍塌度。這三個因素是(shi)(shi)互相關聯的(de)(de)(de)密不(bu)可(ke)分。骨(gu)(gu)料(liao)(liao)(liao)(liao)的(de)(de)(de)等(deng)級(ji)配備，骨(gu)(gu)料(liao)(liao)(liao)(liao)的(de)(de)(de)最大的(de)(de)(de)顆粒徑(jing)(jing)是(shi)(shi)受輸送(song)管(guan)的(de)(de)(de)限(xian)制，卵(luan)石(shi)骨(gu)(gu)料(liao)(liao)(liao)(liao)最大顆粒徑(jing)(jing)不(bu)超過管(guan)徑(jing)(jing)的(de)(de)(de)三分之(zhi)一，碎石(shi)最大的(de)(de)(de)粒徑(jing)(jing)不(bu)超過管(guan)徑(jing)(jing)的(de)(de)(de)四分之(zhi)一，內(nei)徑(jing)(jing)125mm的(de)(de)(de)輸送(song)管(guan)允許通過最大骨(gu)(gu)料(liao)(liao)(liao)(liao)粒徑(jing)(jing)為45mm卵(luan)石(shi)。碎石(shi)為30mm。骨(gu)(gu)料(liao)(liao)(liao)(liao)按料(liao)(liao)(liao)(liao)徑(jing)(jing)可(ke)分為粗骨(gu)(gu)料(liao)(liao)(liao)(liao)和細骨(gu)(gu)料(liao)(liao)(liao)(liao)兩種。粗骨(gu)(gu)料(liao)(liao)(liao)(liao)的(de)(de)(de)形狀有卵(luan)石(shi)，碎石(shi)等(deng)，卵(luan)石(shi)骨(gu)(gu)料(liao)(liao)(liao)(liao)可(ke)泵(beng)性(xing)好，碎石(shi)骨(gu)(gu)料(liao)(liao)(liao)(liao)可(ke)泵(beng)性(xing)差一點。泵(beng)送(song)砼的(de)(de)(de)要求粗骨(gu)(gu)料(liao)(liao)(liao)(liao)的(de)(de)(de)空隙進(jin)可(ke)能(neng)小，其級(ji)配應(ying)接連而均勻(yun)，才能(neng)以較(jiao)小的(de)(de)(de)水(shui)泥用量(liang)，及較(jiao)低(di)的(de)(de)(de)沙率獲得較(jiao)好的(de)(de)(de)可(ke)泵(beng)性(xing)
