水穩(wěn)碎石強(qiáng)度形成及對材料的技術(shù)要求

來源:http://m.yuanchuodian.cn/ 日期:2022-10-07
隨著高等級公路的發(fā)展及公路工程建筑材料的不斷進(jìn)步,作為半剛性路面基層的水泥穩(wěn)定碎石越來越被廣泛應(yīng)用,作為承載層的水硬性結(jié)合料顯的尤為重要。下面濟(jì)南水穩(wěn)料生產(chǎn)廠家來講講水穩(wěn)碎石強(qiáng)度形成及對材料的技術(shù)要求。
With the development of high-grade highways and the continuous progress of highway engineering construction materials, cement stabilized macadam, as the semi-rigid pavement base, is more and more widely used. As the hydraulic binder of the bearing layer, it is particularly important. Next, Jinan water stabilized macadam manufacturer will talk about the strength formation of water stabilized macadam and the technical requirements for materials.
水穩(wěn)碎石強(qiáng)度形成:
Formation of water stabilized macadam strength:
水泥穩(wěn)定碎石是以級配碎石作骨料,采用一定數(shù)量的膠凝材料和足夠的灰漿體積填充空隙,形成板體后具有較高的強(qiáng)度、水穩(wěn)定性、抗?jié)B性和抗凍性。
Cement stabilized macadam is made of graded macadam as aggregate, and a certain amount of cementitious material and sufficient mortar volume are used to fill the gap. After forming the slab, it has high strength, water stability, impermeability and frost resistance.
水穩(wěn)碎石作為水泥穩(wěn)定土中的一種被廣泛應(yīng)用有著其顯著的優(yōu)點(diǎn)。良好的粗細(xì)集料搭配使水穩(wěn)碎石成為一種骨架密實(shí)型結(jié)構(gòu)。
As a kind of cement stabilized soil, water stabilized macadam is widely used with its remarkable advantages. The good mix of coarse and fine aggregates makes the water stabilized macadam a skeleton dense structure.
水穩(wěn)碎石對材料的技術(shù)要求:
Technical requirements for materials of water stabilized macadam:
水泥劑量是影響強(qiáng)度的關(guān)鍵因素,水泥劑量不等,其強(qiáng)度從幾兆帕大到幾十兆帕。作為無機(jī)結(jié)合料粒料,在滿足強(qiáng)度條件下合理的水泥劑量不僅對經(jīng)濟(jì)效益而且對工程都有好處。水泥用量一般為混合料的3%~7%。
The cement dosage is the key factor affecting the strength. The cement dosage varies from several MPa to tens of MPa. As an inorganic binder aggregate, the reasonable cement dosage under the condition of meeting the strength is not only beneficial to the economic benefit but also to the project. The cement consumption is generally 3%~7% of the mixture.
濟(jì)南水穩(wěn)料
水穩(wěn)定性主要是研究水穩(wěn)碎石在飽和水不利情況下,判斷其有足夠的強(qiáng)度。在7天無側(cè)限強(qiáng)度試驗(yàn)中已經(jīng)作了檢驗(yàn)。基層材料中石灰粉煤灰粒料,水泥粒料水穩(wěn)定性好。
Water stability is mainly to study the water stabilized macadam under the unfavorable condition of saturated water and judge that it has sufficient strength. It has been checked in the 7-day unconfined strength test. Lime fly ash granular material and cement granular material in the base material have good water stability.
抗沖刷能力由于表層水的滲入,基層表面積水容易產(chǎn)生沖刷,造成路面病害,如唧漿,坑槽等。對于同一種穩(wěn)定粒料而言,其沖刷程度隨水泥劑量增加而減小,水泥劑量在4%-5%以上時(shí)抗沖刷能力大幅提高。
Erosion resistance: due to the infiltration of surface water, the accumulated water on the surface of the base course is easy to erode, causing pavement diseases, such as grout pumping, pits, etc. For the same stable granular material, its scouring degree decreases with the increase of cement dosage, and the anti scouring ability is greatly improved when the cement dosage is above 4% - 5%.
所以在原材料選擇上,嚴(yán)格控制細(xì)集料小于0.075mm的顆粒的含量和選擇一個(gè)合適的水泥劑量為公路基層質(zhì)量,提高奠定基層。
Therefore, in the selection of raw materials, the content of fine aggregate particles less than 0.075mm shall be strictly controlled and a suitable cement dosage shall be selected to improve the quality of highway base course.
通過水穩(wěn)碎石強(qiáng)度形成及對材料的技術(shù)要求的內(nèi)容了解,就要在材料、結(jié)構(gòu)及施工工藝上提高水穩(wěn)碎石基層質(zhì)量,減少水泥穩(wěn)定碎石的施工中產(chǎn)生的病害,避免人為因素而產(chǎn)生早期破壞。關(guān)注我們http://m.yuanchuodian.cn,了解更多!
Through the formation of the strength of water stabilized macadam and the understanding of the content of the technical requirements for materials, it is necessary to improve the quality of water stabilized macadam base in terms of materials, structure and construction technology, reduce the diseases generated in the construction of cement stabilized macadam, and avoid early damage caused by human factors.
