利文斯敦水泥短缺減緩公路建設進程
這將嚴重影響利文斯敦的公路覆蓋工作,項目管理人員告訴委員會,承建商現(xiàn)在只能得到上星期三分之一的水泥,。
水泥供應商的代表,Ron Knapp先生說,水泥短缺從佛羅里達蔓延到了加利福尼亞。他說,這不僅會影響公路承建商們使用水泥(穩(wěn)定)土,還會影響其他人使用硅酸鹽水泥。同時,他還說,Knapp氏公司,即Buzzi Unicem USA公司, 是政府的四家水泥供應公司之一。Knapp說,因為路易斯安那沒有水泥生產廠,他們要從象泰國那么遠的地方進口水泥。
他說,水泥短缺在很大程度上是由中國的快速發(fā)展造成的。除了抬高運費,他們同時還消耗世界45%的水泥。對負責擴展路面重鋪工程的Barriere 建筑公司來說,水泥短缺在星期五“開頭”,項目管理人Brian H. Kilgen告訴委員會。Kilgen說,盡管水泥短缺臨近,Barriere 建筑公司一直沒受影響,直到星期五他們的水泥供應中斷。 按從水泥公司能得到的水泥推算,筑水泥土工人下星期只能工作兩天。盡管路面是用瀝青鋪,但要用水泥土做地面的地基。Kilgen說,他們本來計劃十一月完成教區(qū)的公路鋪設,現(xiàn)在可能要到明年才行完成。
Alvin Fairburn 工程師告訴委員會,現(xiàn)在可能不得不用水泥和窯渣的混合物來代替水泥土鋪設公路地基。他說,在推薦使用前,他要看該混合物測試結果。

Cement shortage may slow roadwork
By BOB ANDERSON
Florida parishes bureau
LIVINGSTON -- A major shortage of cement caused a Louisiana supplier to ration the cement it sells to contractors and concrete companies, a representative of the firm told the Livingston Parish Council's Road Committee on Wednesday.
That could have a significant impact on Livingston Parish's road overlay work, since the contractor now can get only about a third of the amount of cement it had been using through last week, the project manager told the committee.
The cement shortage extends from Florida to California, Ron Knapp, a representative of the cement supplier, said after the meeting.
He said it will affect not only road contractors using soil cement, but other users of Portland cement as well.
Knapp's company, Buzzi Unicem USA, is one of four cement suppliers in the state, he said.
Because Louisiana no longer has any cement producers, Knapp said, his company has been importing cement from as far away as Thailand.
The shortage is being driven to a great degree by rapid development in China. In addition to tying up shipping, China is consuming about 45 percent of the world's supply of cement, Knapp said.
For Barriere Construction, which is handling the parish's extensive road resurfacing project, the cement shortage "came to a head" on Friday, project manager Brian H. Kilgen told the committee.
Though aware of an impending shortage, Barriere Construction was not affected until Friday, when its supply of cement was cut, Kilgen said.
Kilgen said Barriere's soil cement crews will be able to work only two days next week, based on the amount of cement the company will be able to obtain.
Though the roads are being resurfacedwith asphalt, soil cement is used in the road base.
Kilgen said Barriere had expected to finish the parish's road work by November, but the cement shortage could push the project well into next year.
Engineer Alvin Fairburn told the committee it may be faced with having to use a mixture of cement and a suitable kiln slag as a substitute for traditional soil cement applied to road bases.
He said he is waiting to see the results of state testing on the mixture before making such a recommendation.
Councilman A.C. "Buddy" Mincey said he also wants to see how it has worked elsewhere before approving use of the mixture.
