關於「姑婆芋葉造型踏墊」和「Hypertufa 土盆工藝」的技術、配方。
🌿 鄉間全能顧問分享：南港村的葉模工藝與配方變通
大家好，我是你們的鄉間顧問，大樂兄最近想在農場打造一條美麗又耐用的姑婆芋葉造型步道。
我們在討論過程中，發現了兩種截然不同的水泥工藝：一種是結構耐用型的踏墊，另一種是輕量美觀型的園藝土盆。
這裡就來給大家分析這兩種做法的區別和實務重點，讓大家都能做出堅固又漂亮的鄉村作品。
一、承重型：姑婆芋葉造型踏墊（花園步道用）
如果你像大樂兄一樣，需要做一塊能讓人踩踏、長期耐用的步道踏墊，配方就必須符合工程強度標準。
核心原則：堅固耐用是第一要務
踏墊要承受重量、抵抗南投梅雨和日曬，絕對不能採用強度低的配方。
* 基礎配方建議： 採用標準的水泥砂漿比例。
* 水泥：沙子 \approx 1 : 3。
* 變通提醒： 絕對不能用含有泥土、有機物或黏土的土壤來代替沙子，因為這會嚴重破壞水泥的硬化過程，導致踏墊崩解。
* 穩固結構的秘訣（尖底設計）：
* 大樂兄採用了「尖字型」底座的設計，這是一個高明的做法，能讓踏墊像地錨一樣插入土壤，增加抗晃動和抗沉降的能力。
* 安裝重點： 尖底置入預挖的導孔後，周圍的回填土必須使用粗砂或小碎石徹底夯實，確保踏墊與土壤緊密貼合，否則一踩就會搖晃。
* 強度升級：加入粗骨材：
* 如果踏墊厚度超過五公分，可以加入乾淨的天然石頭或舊水泥塊來增加強度和節省水泥。
* 操作重點： 骨材必須徹底洗淨，並確保其被水泥砂漿完全包裹，距離邊緣至少預留一點五公分。這樣能增加抗裂性，但切記不能讓骨材外露。
* 最重要的養護：
* 任何水泥製品在最初七天都必須保持潮濕並遮陰，防止水分蒸發太快而產生龜裂。
* 最終強度： 至少要等待 28 天，踏墊才能達到其設計強度，期間搬運需輕放。
二、輕量型：Hypertufa 土盆工藝（園藝裝飾用）
如果你想製作的是不承重、追求自然粗獷質感的花盆、燭台或裝飾石像，那麼可以嘗試這種 Hypertufa 工藝。
核心原則：追求粗糙、輕量與透氣感
這種工藝的目標是模擬天然石灰華或風化石的質感，因此配方中會加入輕質填充料。
* 材料與配方： 這種工藝的關鍵在於使用泥炭蘚來提供輕量和多孔的質感。
* 標準比例： 水泥：沙子：泥炭蘚 \approx 1 : 1 : 1。
* 進階比例： 想要更輕、更粗糙，可增加泥炭蘚比例至 1 : 1 : 2。
* 在地變通： 在缺乏泥炭蘚時，可以考慮用曬乾的椰殼纖維或乾淨的細木屑來替代，但木屑會進一步降低強度。
* 操作重點：水量的控制：
* 這是 Hypertufa 最難掌握的地方。泥炭蘚吸水力極強，必須提前充分濕潤。
* 攪拌訣竅： 總水量要少，拌好的狀態應該是「像麥片粥一樣，能塑形但不會流動」。水太多，脫模時容易破碎。
* 脫模與強度風險：
* Hypertufa 的硬化速度比純水泥慢得多，因為有機質會延緩水化。
* 脫模時間： 小件作品（如燭台）至少要等 48 小時（兩天）才能輕輕取出。大型花盆可能需要更久。
* 用途限制： 由於強度較低，這種成品只能作為裝飾品，不能作為結構支撐或承重踏墊。
總結來說，無論是做堅固的踏墊還是輕量的花盆，關鍵都在於釐清你的用途，然後選擇正確的骨材和比例。希望這些經驗分享能幫助你在南港村的農場創作更多漂亮又實用的水泥工藝品！

FINISHED PIECES
Thank you for stopping by and checking out my finished pieces. I can't tell you how much fun I've had making them. Hope you'll come back often as there are lots of projects to make before winter(and during LOL). Hope you have enjoyed the pictures and if you have any comments or suggestions please drop me an email.
01 -我用了Folgers咖啡（大）測量每個泥炭蘚，沙子和水泥，這給了我兩個11 × 11的墊腳石 。您已經倒推玻璃深，當你把刷到它帶來的水泥玻璃
02--This is my second project using the same measurements as I did with the stepping stones but i used a little too much water. When I took it off the mold and was sanding it i popped a hole in the side. I've matched it and it seems to be holding water now.
02 -這是我的第二個項目使用相同的測量，作為我的墊腳石，但我用了一個有點太多水。當我把它的模具，並打磨它，我突然出現在側孔 。我匹配，似乎要水。
03--These are the first of the Grots that I've made. They were so much fun to build then mold the faces. Don't really like the clear eyes but it's all that I had at the time.
03 -這是我Grots的第一個。他們這麼多的樂趣，然後建立模具的面孔 。真的不一樣清澈的眼睛，但它的全部，我當時有
04--I liked how the bird bath turned out so decided to add some color and make this stepping stone and as it turns out the yellow glass stands out better than I thought.
04 -我很喜歡鳥浴如何橫空出世，以便決定添加一些色彩，使這個踏腳石，因為它原來的黃色玻璃脫穎而出比我的想法。
05--I cut out this pattern on foam to give it the raised effect but the mold was only good for one use.
05 -我砍了這種格局對泡沫給它提出的效果，但模具是只有一個使用
06--This is my planter using Hpertufa and the small recycling box for the mold. I have not planted anything into yet but did place a basket of flowers in it for this year. I used the rocks I made with the bird bath as legs to keep it off the ground.
06 -這是我使用Hpertufa和模具的小型回收箱的播種機。我還沒有到尚未種植任何東西，但沒有到位，今年一籃子鮮花在它。我使用的岩石，我與鳥浴腿保持它離地面
07--I saw this on Efildoog's website and had to make it for my yard. It's only been out in the yard a short time but it sure does make people stop and look. :+) 07 - Efildoog的網站上我看到這一點，使我的院子裡 。只有在院子裡很短的時間，但它確實讓人們停下來看看
****************************************
Well as promised more pictures of the projects that I've done during August. Most of the projects where made with 2 peat moss then one of each sand and cement also I used a courser sand for some of the later projects.
。：+）******* 以及承諾的更多圖片我已經在8月完成的項目 。2泥炭蘚然後每個沙子和水泥，我也為以後的項目一個駿馬砂項目。 -------------------- -------------------------------------
---------------------------------------------------------
08--I couldn't wait to see what it would look like with flowers in it so it was handy that this basket fit it almost perfect. 08 -我不能等待，看看有什麼會它看起來像鮮花，所以這是非常方便，這個籃子適合近乎完美的
09--These were made from what was leftover when I made the planter in the next picture. I thought I would be able to plant small Marigolds in them and put them on my front step next year. 09 -這些是吃剩的下一張照片時，我在種植 。我想我可以種植在他們的小萬壽菊，並把它們在我的前面一步明年
10--I made this in a cardboard box lined with plastic putting in the base then put another box (that is in plastic) inside building the sides up, you have to have something heavy in the second box to hold it in place and so the sides don't bow out. 10 -我在一個紙箱內襯塑料基地，然後把另一箱（塑料）內建設方面，已經有重的東西在第二個框中舉行的地方，所以雙方不低頭了。
11--I love my candle light so that's why I made this one in amber for outside with the copper leaves. Being outside in the elements the copper is turning green which I think adds a nice touch. 11 -我愛我的燭光，所以這就是為什麼我以外這個琥珀中銅葉。銅返青，我認為在元素之外，增加了一個很好的接觸。
12--I really wasn't sure what I was going to do with these molds when I bought them but they make nice candle holders. I did mess up by taking them out of the mold to soon I have to leave them in there for at least 48 hrs. or the leaves break off. That's why you only see 3 instead of 4. I watched my girl friend Kris carve an owl into her Hypertufa bird bath so I gave it a try with the 8 inch stepping stone. 12 -我真的不知道我是我買的時候他們做這些模具的，但他們做出漂亮的燭台。我沒惹出來的模具很快，我要在那裡至少48小時，他們離開。或樹葉折斷。這就是為什麼你只能看到3而不是4。我看著她的Hypertufa鳥浴我的女孩的朋友克里斯雕刻成一隻貓頭鷹，所以我給它一個嘗試用8英寸的踏腳石。
14--I think I'm going to let the leaves wear off naturally I did take a knife to the sides to cut off the excess and help round them off. The two candle holders where made out of sundae cups from when we went for ice cream just the perfect size.
15--Objects may appear larger than they actually are LOL 16--I made the grots quite awhile back and just got around to making it's face last week, for the taller one I used iridized black glass and other has two stones for eyes that were found in our yard. The smaller flower pot on the bench was made for Kim as was the bird's water dish.
