Pumice sand replacement with normal-weight one considerably increases bond strength.

All-LWASCC bond strength (splitting) is by approx. 80% lower than that of NWSCC.

All-LWASCC bond strength (pull-out) is by max. 30% lower than that of NWSCC.

Bond length increase leads to decreasing of the max. normalized bond stress, class="mathmlsrc">title="View the MathML source" class="mathImg" data-mathURL="/science?_ob=MathURL&_method=retrieve&_eid=1-s2.0-S0950061816303762&_mathId=si1.gif&_user=111111111&_pii=S0950061816303762&_rdoc=1&_issn=09500618&md5=fa8112b75e362584273cd45a505a3401">class="imgLazyJSB inlineImage" height="15" width="17" alt="View the MathML source" style="margin-top: -5px; vertical-align: middle" title="View the MathML source" src="/sd/grey_pxl.gif" data-inlimgeid="1-s2.0-S0950061816303762-si1.gif">class="mathContainer hidden">class="mathCode">τu.
