مقاومت فشاری و کششی گچ

معمولا مصرف گچ در ساختمان برای اعضاء باربر نبوده بلکه فقط برای نازک کاری مصرف می شود بدین لحاظ اگر ملات گچ پس از سخت شدن و خشک شدن بتواند وزن خودرا تحمل نماید کافی می باشد در آزمایش هایی که بعمل آمده نشان می دهد که مقاومت فشاری گچ سخت شده بیش از 30 کیلو گرم بر سانتیمتر مربع و مقاومت کششی آن بیش از 5 کیلوگرم برسانتی متر مربع می باشد که این هر دو برای مصرف گچ در ساختمان برای نازک کاری کافی است.

برای ساخت قطعات نیز بهتر است از گچ های با کیفیت بالا استفاده گردد.  درصورتی که سبک بودن قطعات گچی مهم باشد بهتر است از گچ با دانه بندی ریز استفاده گردد و درصورتی که مقاومت مهم باشد بهتر است از گچی با دانه بندی درشت استفاده گردد.

هر چقدر درصد خلوص گچ بالاتر باشد ( ناخالصی کمتری داشته باشد ) و در تهیه و تولید آن از روش های جدید استفاده شده باشد مقاومت فشاری، کششی و خمشی آن بالاتر خواهد بود. همچنین می توان با استفاده از افزودنی های شرکت مهندسین مشاور کیا عمران مقاومت فشاری و کششی  گچ را سه تا پنج برابر افزایش داد. جهت آشنایی با این افزودنی ها و یا سفارش آنها به سایت www.4civil.ir یا www.gatch.ir  مراجعه فرمایید.
