水穩(wěn)料的使用您要了解什么？

“濟(jì)南水穩(wěn)料”是在一些建筑材料中（碎石土，碎石等），加入一定摻量的水泥（一般來講這個摻量沒有混凝土高，在5%左右，造價也比混凝土便宜），達(dá)到一定的穩(wěn)定效果。一般來講作為建筑的基層或者路面基層使用。具有一定程度的強(qiáng)度和隔水效果。而且剛度不是很大，具有一定的柔性作用。

"Jinan water stabilized material" is to add a certain amount of cement into some building materials (crushed stone soil, crushed stone, etc.) (generally speaking, this amount is not as high as concrete, about 5%, and the cost is also cheaper than concrete) to achieve a certain stability effect. Generally speaking, it is used as the base course of building or pavement. It has a certain degree of strength and waterproof effect. Moreover, the stiffness is not very large and has a certain flexibility.

水穩(wěn)的配合比應(yīng)事先在實(shí)驗(yàn)室內(nèi)進(jìn)行配合比試配，以確定水泥摻量和粗細(xì)集料比例，同時確定大干密度。量大可采用水穩(wěn)攪拌站拌合。

The mix proportion of water stabilized concrete shall be tested in the laboratory in advance to determine the cement content and the proportion of coarse and fine aggregates, as well as the large dry density. Water stabilized mixing plant can be used for mixing in large quantities.

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骨料的空隙，按嵌擠原理攤鋪壓實(shí)。其壓實(shí)度接近于密實(shí)度，強(qiáng)度主要靠碎石間的嵌擠鎖結(jié)原理，同時有足夠的灰漿體積來填充骨料的空隙。

Cement stabilized macadam uses graded macadam as aggregate, uses a certain amount of cementitious material and sufficient mortar volume to fill the gap of the aggregate, and paves and compacts according to the principle of inlaying. Its compactness is close to compactness, and its strength mainly depends on the principle of inlaying and locking between crushed stones, and there is enough mortar volume to fill the gap of aggregate.

它的初期強(qiáng)度高，并且強(qiáng)度隨齡期而增加很快結(jié)成板體，因而具有較高的強(qiáng)度，抗?jié)B度和抗凍性較好。水穩(wěn)水泥用量一般為混合料3%~6%,7天的無側(cè)限抗壓強(qiáng)度可達(dá)1.5~4.0mpa，較其他路基材料高。水穩(wěn)成活后遇雨不泥濘，表面堅(jiān)實(shí)，是高級路面的理想基層材料。

Its initial strength is high, and its strength increases with age and quickly forms a plate, so it has high strength, good permeability and frost resistance. The dosage of cement stabilized by water is generally 3%~6% of the mixture, and the unconfined compressive strength in 7 days can reach 1.5~4.0 mpa, which is higher than other subgrade materials. After water stabilization, it is not muddy in the rain and has a solid surface. It is an ideal base material for high-grade pavement.

根據(jù)交通部《公路路面基層施工技術(shù)規(guī)范》規(guī)定，道路中采用的水泥穩(wěn)定碎石均屬中粒土，由于水穩(wěn)中含有水泥等膠凝材料，因而要求整個施工過程要在水泥終凝前完成，并且一次達(dá)到質(zhì)量標(biāo)準(zhǔn)，否則不易修整。

According to the Technical Specifications for Construction of Highway Pavement Base Course issued by the Ministry of Communications, the cement stabilized macadam used in the road belongs to medium-grained soil. Because the cement and other cementitious materials are contained in the water stabilized macadam, the whole construction process is required to be completed before the final setting of the cement and meet the quality standards at one time, otherwise it is not easy to repair.

因而施工中要求加強(qiáng)施工組織設(shè)計(jì)和計(jì)劃管理，增加現(xiàn)場施工人員的緊迫感和責(zé)任感，加快施工進(jìn)度，加大機(jī)械化施工程度，提高機(jī)械效率。水穩(wěn)的施工方法也符合現(xiàn)代化大規(guī)模機(jī)械化發(fā)展的方向，因而水穩(wěn)在公路工程中的應(yīng)用會得到很快推廣。有需求就來找我們http://drafti.cn咨詢吧。

Therefore, during the construction, it is required to strengthen the construction organization design and plan management, increase the sense of urgency and responsibility of the on-site construction personnel, speed up the construction progress, increase the degree of mechanized construction, and improve the mechanical efficiency. The construction method of water stabilization is also in line with the development direction of modern large-scale mechanization, so the application of water stabilization in highway engineering will be rapidly promoted.
