樓板緩衝材工法對地坪瓷磚劣化之影響研究－以抗壓強度為例

民國110年初，集合住宅與辦公室隔音性能法規的上路，加入新式的樓板隔音施工的工法。在樓板的飾面材料，瓷磚的討論議題，「膨拱」便是大眾最關心的現象，在新式的樓板隔音工法上也有對此現象的疑慮，為了解決這些疑問，本研究透過實驗去嘗試了解壓層與隔音墊的各種組合，找到整體樓板構造最脆弱的位置，並分析風險與對策，最後提出改善之對策。本研究專注於壓層上造成的風險，進行構造上的抗壓實驗模擬，討論訪談對象P案場出現的「膨拱」現象，裂縫破壞至壓層部位，是否與隔音墊施作狀態、壓層施作配比有關聯，並且比較法規標準施作第二目與無隔音墊變因的分析。作為P隔音墊的施作變因額外分為4種，平舖、皺褶、中央交疊與邊部交疊，探討高塑性材料的自由運用對壓層受壓時的強度影響。經實驗後，發現壓層砂漿會因為塑性隔音墊材料特性產生的不平整狀況，導致抗壓強度降低，此外，受壓面的凸起面積越大，抗壓破壞的風險越大，而壓層水灰比越低，抗壓強度更是大量折減。作為受壓面的構造，建議保持壓層施作面的平整，即隔音墊的平整，以減少壓層受壓不均產生的裂縫；而泥作工班所澆置的水泥砂漿，建議以約0.5～0.8的水灰比進行施作，讓工作度、強度與水化作用程度都到達一定值。

In 2022, regulations of sound insulation have been legislated in Taiwan. In order to meet with the new standard, the urge to renew process of tile production is undeniable. Besides, the problem about the bulging of interior tile remains a sticky issue to be solved. This research mainly focuses on the concrete used in producing tiles. By conducting pressure experiments, we will observe if the compression resistance of insulation module will be affected by different kind of acoustic insulation mat. Besides, there are other factors considered to affect the strength of the insulation module which will be discussed in the article, including: water-cement ratio, and production process of insulation module. In conclusion, acoustic insulation module is highly affected by the flatness of insulation mat. The insulation mat rough surface will make mortar weak on press, and lead to bulging issue more easily. Moreover, water-cement-ratio also plays a critical role in the process. The amount of water needs to maintain at a reasonable balance, where it not only is able to fully sustain the hydration reaction, but also hold the standard of resistance and workability.
