在我国,用红砖做房屋已经有2000多年的历史了。红砖曾在建筑领域被广泛使用,有稳定性高、性能好、性价比高等特点。然而,不知从何时起,人们在建房时很少再见到这种实心红砖。而改用水泥砖、多孔砖等,国家也开始禁止烧制红砖。那么,为什么要禁止使用红砖呢?原来,红砖的原料是粘性土,而为了烧制红砖,需要专门搭建砖窑开山挖土,对粘土资源燃料的消耗都是很大的。红砖烧制的过程也容易引发煤炭资源的浪费、空气污染等问题。另一方面,红砖的隔热性能并不如水泥砖与空心砖。在红砖建造的房子中,人们常常感到冬天特别冷,而夏天又特别炎热。随着城市化进程的发展,出现了越来越多几十层甚至上百层的高楼。总的来说,红砖作为传统的建房材料,有一定的优势。从远古的石头到古代的木材,从红砖再到水泥砖、多孔砖,如今各种各样的新型建材可谓层出不穷。但红砖坚固,如果用红砖拍头,大概可以把人拍到怀疑人生。另外红砖寿命长、外观优美,在人们心中仍然占着无法比拟的位置。更多精彩知识问答,请关注我:找靓机科普(zljkepu)

1、红砖厂前些年经常会收留一些被拐卖的人(个别儿童,大部分为思想不健全的人),也成了一些有过罪行躲避的良好场所,也出现过好些命案。2、烧制红砖青砖,都需要用挖掘优质的粘土,土地污染。烧制需要大量的煤造成空气污染严重(觉得比工厂污染小的多),不巧死在了国家政策前面(不符合经济发展弊端太多)。3、成本,参考第一条:招工困难,没人干活了,煤炭涨价,国家整治一系列问题。入不敷出(烧制砖窑典型的苦力活,给你个小拉车拉上一天试试,没把子力气根本拉不动那一车)4、国家没说不允许,只是因为这行做着很不容易,老百姓都不愿意自家的地被挖成大坑。开窑厂还经常受到环保局工商局光顾。想想还是做其它的好。

五十年前盖新房,多用土呸来垒墙。四十年前把房盖,推广蓝砖都喜爱。三十年前盖新房,时兴红砖来彻墙。近几年,抓环保,红砖砖窑已很少。全是矿渣水泥砖,经济实惠也美观。既能把房给建好,还能把废变成宝。不是红砖不见了,而是已经淘汰了。
4、精彩回答:
第一,红砖原材料单一,不能过度开采造成地质危害。第二红砖比较重,运输和建高都有压力。第三,红砖房冬寒夏热。最大原因还是开采过大,还有太重不适合建高。

5、精彩回答:
国家目前出台政策不准煅制红砖,目的并不是单纯阻止人们建红砖房子,它除了起到抑制人们建房,更有目的消灭库存,而这对眼下的房价有起到防止往下滑或者滑得太快的作用,因为现在国家正在整顿住房政策,…
红砖,别名黏土砖,是以黏土、页岩、煤矸石、细沙等为原材料,经粉碎、混合捏练后压制成型,干燥后再在900度高温以氧化焰烧制而成的烧结成型的建筑砖块。建出的房子也很好看,可为什么国家不允许使用其建房了呢?



总的来说,无非是使用红砖建房的弊大于利,那有哪些弊端呢?
高损耗:由于烧制红砖的材料是黏土,在挖采黏土时严重损毁良田。
高污染:红砖的烧制会要用到煤炭,在烧制过程中也会产生大量的废气和废水,严重污染环境。
承重能力没有钢筋混凝土的好,侧面抗击能力也很差。
工序复杂:由于红砖为小块材料,必须要现场湿作业,在烧制和砌墙过程中很危险。
那没了红砖我还能用什么建房呢?有灰砂砖、水泥砖、多孔砖等。
