の発泡体と、現場で発泡させるものとが知られている。Conventionally, as this type of heat insulating material, organic foams processed into plate shapes and those foamed on-site are known.
そして、前者は、断熱の施工に当たっては、予め型枠工
事で断熱材を取り付け、コンクリート打設時に必要箇所
に打ち込まれる。In the case of the former, when constructing insulation, the insulation material is installed in advance through formwork construction, and then poured into the required locations during concrete pouring.
又、後者は、コンクリート打設後のコンクリート表面に
吹付は施工されるかコンクリート壁体と仕上材との空隙
に充填施工される。The latter is applied by spraying onto the concrete surface after concrete placement, or by filling the gap between the concrete wall and the finishing material.
これらの有機の発泡体としては、プラスチックフオーム
が知られている。その−例を挙げると、次の通りである
。Plastic foams are known as these organic foams. An example of this is as follows.
硬質ウレタンフオームの場合、比重が０．０３、圧縮強

０．０２５Ｋｃａｌ／ｍ、ｈ、 ’Ｃ，又、ポリスチレ
ンフオームの場合には、比重が０．０３、圧縮強度２．
５〜３．ＯＫｇｆ／ｃｆｆｌ、熱伝導率０．０２５〜０
．０３０Ｋｃａｌ／ｍ、ｈ、’ｃである。In the case of hard urethane foam, the specific gravity is 0.03 and the compressive strength is 1.4 to 2. OKgf/Cpo, thermal conductivity 0.020~
0.025 Kcal/m, h, 'C, and in the case of polystyrene foam, the specific gravity is 0.03 and the compressive strength is 2.
5-3. OKgf/cffl, thermal conductivity 0.025-0
．． 030Kcal/m, h, 'c.
然し、従来の断熱材では、以下に示す如く、施工上及び
耐火上の問題がある。However, conventional heat insulating materials have problems in terms of construction and fire resistance, as described below.
即ち、施工上の問題点としては、■強度が弱い。That is, the problems in construction are: (1) The strength is weak.
■型枠取付及び打込みに費用が増加する。■型枠脱型の
際に断熱材を損傷する、ことが挙げられる。■Costs will increase for formwork installation and driving. ■ Damage to the insulation material when removing the formwork.
又、耐火上の問題点としては、■有機の発泡体であるた
め、可燃性であり、燃焼した際に有毒ガスを発生するも
のが多い。■主材料が有機であるため、燃え易い、こと
が挙げられる。In addition, fireproofing problems include: (1) Since they are organic foams, they are flammable, and many of them generate toxic gas when burned. ■Because the main material is organic, it is easily flammable.
又、無機質系の発泡断熱材の開発も試みられているが断
熱性能や強度的に問題があると共に、施工性、コスト面
で難がある。Further, attempts have been made to develop inorganic foam insulation materials, but they have problems in terms of insulation performance and strength, as well as problems in terms of workability and cost.
又、従来軽量化と断熱を考慮したものとして、パーライ
トを添加したパーライトモルタルが知られている。この
パーライトモルタルの性質をセメント１に対してパーラ
イト３の場合の容積比配合に基づいて示すと次の通りと
なる。曲げ強度（４週間） ２９．７Ｋｇｆ／ｃＩｌＮ
、圧縮強さ（４週間） １１６Ｋｇｆ／ｃｌ、気乾比重
１．０６ 、熱伝導率０．１８Ｋｃａｌ／ｍ、ｈ、 ’
Ｃとなる。Furthermore, pearlite mortar to which pearlite is added is known as a mortar that takes weight reduction and heat insulation into consideration. The properties of this pearlite mortar are shown below based on the volume ratio of 1 part of cement to 3 parts of pearlite. Bending strength (4 weeks) 29.7Kgf/cILN
, Compressive strength (4 weeks) 116 Kgf/cl, Air dry specific gravity 1.06, Thermal conductivity 0.18 Kcal/m, h, '
It becomes C.
然し、パーライトモルタルは、熱伝導率０．１８Ｋｃａ
ｌ／ｍ、ｈ ’Ｃと上述したプラスチックフオームに比
して大きいため、プラスチックフオームに比して断熱性
が劣っている。However, pearlite mortar has a thermal conductivity of 0.18Kca.
l/m and h'C, which are larger than those of the above-mentioned plastic foam, so the heat insulation properties are inferior to that of the plastic foam.
又、パーライト自体の比重が０．５〜０．７であるため
、通常では、比重が０．８〜１．４程度のものしか使用
されていない。そして、この軽量モルタルの比重を更に
小さくしようとすると、強度が低下し、施工上からも実
用に供し得なくなる虞がある。Further, since the specific gravity of pearlite itself is 0.5 to 0.7, normally only pearlite with a specific gravity of about 0.8 to 1.4 is used. If an attempt is made to further reduce the specific gravity of this lightweight mortar, the strength will decrease and there is a risk that it may become unusable from a construction standpoint.
