Description
【０００１】
【産業上の利用分野】
この発明は、軽量の瓦下地用モルタルであって、包装時には硬化がなく、開封すると硬化することを目的とした瓦下地用包装モルタルに関する。
【０００２】
【従来の技術】
従来瓦下地のモルタルとして遅延剤を含む包装セメントモルタルが知られていた（特願昭６２−３１２５８５号）。
【０００３】
【発明により解決すべき課題】
前記従来の包装セメントモルタルは炭酸カルシウムを混入してないので、粘度および強度上不十分であった。
【０００４】
また通常の壁下地用又は目地用モルタルは現場で必要材料を混合し、水を入れて練り上げているので、過大に作ると使い終るまでに硬化が始る問題点があり、過小に作ると、混練時間が塗着の作業時間に比し多くなって、効率低下のおそれがあった。更に砂を骨材にしているので重量が大きくなる問題点があった。
【０００５】
【課題を解決するための手段】
然るにこの発明は、軽量骨材を用いる包装モルタルとしたので、必要量宛袋を開けばよく、そのまま使用できると共に、密封すれば保存性よく、かつ軽量となりその上現場混練作業を皆無とし、前記従来の問題点を解決したのである。
【０００６】
即ちこの発明は、硬化遅延剤を添加した包装モルタルの骨材として軽量骨材を使用したことを特徴とした包装モルタルである。
【０００７】
またこの発明は、石灰１〜６重量部、炭酸カルシウム１０〜１５重量部、軽量骨材３〜５重量部、セメント０．１〜０．５重量部、硬化遅延材０．１〜０．３重量部、つなぎ材０．０５重量部および適量の水を混練し、これを包装したことを特徴とする瓦下地用包装モルタルである。前記において硬化遅延剤として糖蜜を使用するが、一般に空気に触れることによって硬化遅延の効果を失う薬剤（例えばポリオール複合体を含むもの）ならば使用することができる。また軽量骨材としてはパーライトに代えて発泡スチロール粒（１〜２ｍｍ球）を用いることができる。
【０００８】
前記におけるモルタルには、つなぎ材（ツタ、繊維など）を入れる場合と、入れない場合とがある。
【０００９】
この発明は、必要とする材料中砂に代えて軽量骨材を用い、かつこれに所定量の硬化遅延剤を混入し、水を加えて混練した後、合成樹脂袋（通気性のない合成樹脂フィルム製）に密封している。
【００１０】
この発明のモルタルは、ラスボードなどに塗着するモルタル、目地モルタルその他一般建築に用いるセメントモルタルの代りに使用することができる。
【００１１】
【作用】
この発明によれば、石灰、炭酸カルシウムなどよりなるモルタルに硬化遅延剤を入れて密封したので、必要な際に必要な量のみを開封して使用し得ると共に、粘着性と強度の優れたモルタルを提供することができる。
【００１２】
【実施例１】
石灰６ｋｇ、炭酸カルシウム１０ｋｇ、パーライト３ｋｇ、セメント０．３ｋｇ、糖蜜２００ｃｃおよびつなぎ材０．０５ｋｇに水３０リットルを入れて均一に混練し、５０ｋｇの混練物を得た。これを厚手（厚さ０．２ｍｍ）の塩化ビニール袋に２５ｋｇ宛包装して製品とした。
【００１３】
前記包装モルタルは、２０日経過後も混練直後と同一の性能が認められたが、３０日経過すると硬化が認められた。また使用残のモルタルは密封保存することにより２４時間経過後の使用に耐えることが認められた。更に塗着後の硬化速度は、硬化遅延剤の入らないモルタルと大差はない。然して硬化開始の日数を長くする為には硬化遅延剤を１０〜２０％増量する必要がある。
【００１４】
従来壁下地として、石灰、軽量骨材、少量のセメント及びつなぎ材の混合物が現場で配合混練され、使用されているが、現場混練のモルタルより均一混合できるのみならず、強度および粘度を安定させることができる。
【００１５】
【比較例】
次にこの発明の実施例と、従来使用されている包装モルタルとの成分比を表１に示す。
【００１６】
【表１】
前記表１の配合により、夫々包装モルタルを製造した所、▲１▼、▲２▼、▲３▼は３０日で硬化がみられたが、従来例は硬化しなかった。尤も▲１▼、▲２▼、▲３▼も２０日位では硬化はみられなかった。そこで硬化遅延剤を若干多く使用すれば、硬化開始の材令を延長することができる。
【００１８】
表１の配合による製品の比重は、従来品に比し、表２のように３０％程度軽量になった。
【００１９】
【表２】
即ち材令により、配合により多少の相違が認められるが、従来例の６２％〜７８％となっている。従って平均的には３０％以上軽量になっていることが認められた。
【００２１】
次にこの発明の製品は、圧縮強度が従来品に比し同等以上である（表３）。その理由は、比較的硬練り状になる為かと思われる。
【００２２】
【表３】
また保存性については、硬化が若干早くなるが（表４）、硬化遅延剤の量を調整することにより、３０日位の保存性は確保できる。
【００２４】
【表４】
【発明の効果】
この発明によれば、従来知られている壁下地用、目地などのモルタルに炭酸カルシウムを添加すると共に、骨材の砂に代えて軽量骨材を用いかつ硬化遅延剤を添加し、これを密封袋により包装したので、壁下地モルタル等の必要時に、包装を開き必要量だけ取出して使用し、残部を再び密封すれば、後日使用することができる効果がある。然して３０％前後軽量となるので取扱いが容易となった。
【００２６】
また炭酸カルシウムを添加したので、モルタルの粘性を増加すると共に強度を増強する効果がある。
【００２７】
この発明のモルタルは従来使用のモルタルに比し強度が大きい。[0001]
[Industrial application fields]
The present invention relates to a lightweight roof tile mortar that is not cured at the time of packaging and is intended to be cured when opened.
[0002]
[Prior art]
Conventionally, a packaging cement mortar containing a retarder has been known as a mortar for roof tiles (Japanese Patent Application No. 62-312585).
[0003]
[Problems to be solved by the invention]
Since the conventional packaging cement mortar does not contain calcium carbonate, the viscosity and strength are insufficient.
[0004]
Also, normal wall mortar or joint mortar is mixed with the necessary materials on site, water is added and kneaded, so there is a problem that curing will start before use, if made excessively, if made too small, The kneading time is longer than the coating work time, and the efficiency may be reduced. In addition, since sand is used as an aggregate, there is a problem that the weight increases.
[0005]
[Means for Solving the Problems]
However, since the present invention is a packaging mortar using a lightweight aggregate, it is sufficient to open the bag for the required amount, and it can be used as it is, and it is well-preserved and lightweight when sealed, and there is no on-site kneading work. It solved the conventional problems.
[0006]
That is, this invention is a packaging mortar characterized by using a lightweight aggregate as an aggregate of the packaging mortar to which a setting retarder is added.
[0007]
In addition, the present invention comprises 1 to 6 parts by weight of lime, 10 to 15 parts by weight of calcium carbonate, 3 to 5 parts by weight of lightweight aggregate, 0.1 to 0.5 parts by weight of cement, and 0.1 to 0.3 of a retarder for hardening parts, ties 0.05 part by weight of an appropriate amount of water were mixed paste, a tile underlayer packaging mortar, characterized in that the packaging it. In the above, molasses is used as a cure retarder, but generally any agent that loses the effect of cure retardance by exposure to air (for example, one containing a polyol complex) can be used. Moreover, as a lightweight aggregate, it can replace with pearlite and can use a polystyrene foam grain (1-2 mm sphere).
[0008]
In the mortar, there is a case where a binder (ivy, fiber, etc.) is put or not.
[0009]
This invention uses a lightweight aggregate instead of the required material sand, mixes a predetermined amount of a curing retarder, adds water, kneads, and then a synthetic resin bag (a synthetic resin without air permeability). (Made of film).
[0010]
The mortar of the present invention can be used in place of mortar to be applied to lathboard, joint mortar and other cement mortar used for general construction.
[0011]
[Action]
According to the present invention, the mortar made of lime, calcium carbonate or the like is sealed with a curing retarder, so that only the necessary amount can be opened and used when necessary, and the mortar has excellent adhesiveness and strength. Can be provided.
[0012]
[Example 1]
30 kg of water was uniformly mixed in 6 kg of lime, 10 kg of calcium carbonate, 3 kg of pearlite, 0.3 kg of cement, 200 cc of molasses and 0.05 kg of binder, and 50 kg of kneaded material was obtained. This was packed into a thick (0.2 mm thick) vinyl chloride bag for 25 kg to obtain a product.
[0013]
The packaging mortar showed the same performance immediately after kneading after 20 days, but hardening was observed after 30 days. In addition, it was confirmed that the remaining mortar can withstand use after 24 hours by sealing and storing. Furthermore, the curing rate after coating is not much different from that of mortar containing no cure retarder. However, it is necessary to increase the amount of the curing retarder by 10 to 20% in order to lengthen the number of days for starting curing.
[0014]
Conventionally, a mixture of lime, lightweight aggregate, a small amount of cement and a binder is used and mixed and used in the field as a base for the wall. be able to.
[0015]
[Comparative example]
Next, Table 1 shows the component ratio between the examples of the present invention and conventionally used packaging mortars.
[0016]
[Table 1]
When the packaging mortar was manufactured according to the formulation shown in Table 1, curing was observed in 30 days in (1), (2) and (3), but the conventional example did not cure. However, in (1), (2), and (3), no hardening was observed in about 20 days. Therefore, if the curing retarder is used in a slightly large amount, the age of curing can be extended.
[0018]
The specific gravity of the product with the composition shown in Table 1 was about 30% lighter as shown in Table 2 than the conventional product.
[0019]
[Table 2]
That is, depending on the material age, some difference is recognized depending on the blending, but it is 62% to 78% of the conventional example. Therefore, on average, it was recognized that the weight was 30% or more.
[0021]
Next, the product of the present invention has a compressive strength equal to or higher than that of the conventional product (Table 3). The reason seems to be because it becomes relatively hard.
[0022]
[Table 3]
As for storage stability, curing is slightly accelerated (Table 4), but storage stability of about 30 days can be ensured by adjusting the amount of curing retarder.
[0024]
[Table 4]
【The invention's effect】
According to the present invention, calcium carbonate is added to a conventionally known mortar for a wall base, joint, etc., a lightweight aggregate is used in place of the aggregate sand, and a setting retarder is added, and this is sealed. Since it is packaged by a bag, when a wall base mortar or the like is needed, it can be used at a later date if the package is opened and used in a necessary amount and the remaining part is sealed again. However, since it is about 30% lighter, it is easier to handle.
[0026]
In addition, since calcium carbonate is added, the viscosity of the mortar is increased and the strength is enhanced.
[0027]
The mortar of the present invention has a higher strength than conventional mortars.
